PHP MySQL Database
With PHP, you can connect
to and manipulate databases.
MySQL is the most popular
database system used with PHP.
What is MySQL?
- MySQL
is a database system used on the web
- MySQL
is a database system that runs on a server
- MySQL
is ideal for both small and large applications
- MySQL
is very fast, reliable, and easy to use
- MySQL
uses standard SQL
- MySQL
compiles on a number of platforms
- MySQL
is free to download and use
- MySQL
is developed, distributed, and supported by Oracle Corporation
- MySQL
is named after co-founder Monty Widenius's daughter: My
The data in a MySQL
database are stored in tables. A table is a collection of related data, and it
consists of columns and rows.
Databases are useful for
storing information categorically. A company may have a database with the
following tables:
- Employees
- Products
- Customers
- Orders
PHP + MySQL Database System
- PHP
combined with MySQL are cross-platform (you can develop in Windows and
serve on a Unix platform)
Database Queries
A query is a question or a
request.
We can query a database for
specific information and have a recordset returned.
Look at the following query
(using standard SQL):
SELECT LastName FROM Employees
The query above selects all
the data in the "LastName" column from the "Employees"
table.

If you don't have a PHP
server with a MySQL Database, you can download it for free here: http://www.mysql.com
Facts About MySQL Database
MySQL is the de-facto
standard database system for web sites with HUGE volumes of both data and
end-users (like Facebook, Twitter, and Wikipedia).
Another great thing about
MySQL is that it can be scaled down to support embedded database applications.
Look at http://www.mysql.com/customers/ for
an overview of companies using MySQL.

Which OS is better for
PHP developer WIndows, Linux or Mac?
Any of them will do
nicely. My answer did get longer than I started out with.
I recommend though that
you get some Unix/Linux experience because 99% of the time your code will run
on Linux server in production.
I have programmed PHP
on all of these and as usual, I prefer using my Mac. But today in 2023 these
systems all work so well, I use the same tools on most systems so I honestly
don’t care. But if I choose myself to do something, I use a Mac. if I do .NET
as well, I might use Windows.
I run all of these
systems at home. It is also a great thing to change environments so you don’t

You already have a version of
mySQL installed on this machine that is using port 3306. Go into the most
recent my.ini file and
change the port to 3307.
Restart the mySQL service and see if it comes up.
You also need to change port

means different things to different people in different companies, but it
usually means automating cloud infrastructure and assisting development teams
in getting software into customers’ hands reliably.
So,
instead of spending time setting up infrastructure, these project ideas are all
focused on deploying software.
Best
DevOps Projects for Beginners
1.
Java Application using Gradle
Gradle
is a well-known build automation tool that works across a variety of platforms
and languages. This project includes establishing a Java application and
breaking it down into subprojects in order to modularize it.
After
completing this project, you will know how to initialize a project as Java
application, run the build and build it’s test report. You will learn the way
to execute a Java application and build it in an archive.
2.
WebServer using Docker
Docker
is a popular container technology for hosting services and applications that
virtualizes operating systems and builds lightweight containers. You will
create a default base image for this project that other developers can use in
their production environments. This project offers the framework for web app
images in Python, Ruby, and Meteor.
On
successful completion of this project, you will be able to reduce the size of
the Dockerfile, shorten the time it takes to write a Dockerfile. Also, you will
learn to correctly setup the base system and reduce the amount of time it takes
to run docker build and the download time.
3.
CI/CD Pipeline using Azure
You’ll
use Azure DevOps Project to set up continuous delivery (CD) and continuous
integration (CI) pipelines in this project. You may get started by using the
provided code. The purpose is to quickly deploy an app to a variety of Azure
services, including App Service, Virtual Machines, and Azure Kubernetes
Services (AKS).
In
this project, you’ll use Azure’s DevOps Starter feature to establish an ASP.NET
sample code, explore the CI/CD pipelines configured by DevOps Starter, commit
code changes and run CI/CD, and configure Azure Application Insights
monitoring.
4.
Jenkins Remoting Project
Jenkins
Remoting is a library and archive for creating a communication layer. TCP
protocols, data streaming, procedure calls, and other features are all
included.

implementation library. Jenkins Remoting can be made compatible with a bus
technology like ActiveMQ or RabbitMQ. You’ll need knowledge of networking
fundamentals, Java, and message queues to execute the task.
5.
CD Pipeline using AWS
You
will develop a continuous delivery pipeline for a small web application in this
project. To store your source code, you’ll first use a version control
system.
Then
you’ll learn how to set up a continuous delivery pipeline that will deploy your
web application automatically anytime your source code is updated. This project
uses GitHub, AWS Elastic Beanstalk, AWS CodeBuild, and AWS CodePipeline.
Best
DevOps Projects for Advanced
6.
Deploying a Containerized Web Application
This
project demonstrates how to package a web application as a Docker container
image and run it on a Google Kubernetes Engine (GKE) cluster. The web
application is then deployed as a load-balanced collection of replicas that can
scale to meet the demands of your users.
This
project will help you in learning of how to package a sample web application
into a Docker image, uploading the Docker image to Artifact Registry, creating
a GKE cluster and deploying it to the cluster, managing autoscaling for
deployment, exposing the app to the internet and deploying a new version of it.
7.
Building Version Control System
You
can use a Version Control System to keep track of your code, inspect multiple
versions of it, switch between them, maintain different versions of it, and
share it with other programmers.
You
will start with the basics and save code in our version control system. You
will have to take the long way to set up a repository in order to do so. From
there, you will figure out how to navigate through history. Then you will
figure out how to handle branching, which is deceptively difficult in and of
itself. You’ll be ready for Git once you’ve finished branching.
8.
Deploying Application Using Kubernetes
In
this project, you are going to use a simple web service which parses user
messages and adds your message to a Redis Server. It is similar to a voicemail
where the users can leave messages.
This
project needs to run the application on Kubernetes, hence dockerizing is the
primary step in this project. Hence, you will learn how to enable the
application to run in docker containers.
9.
Structuring a Terraform Project
In
order to ensure its maintainability and extensibility in day-to-day operations,
Terraform projects must be properly structured according to their use cases and
perceived complexity.
This
project will teach you how to organize Terraform projects based on their
general purpose and complexity. Then, using the more popular Terraform features
such as variables, localities, data sources, and provisioners, you’ll design a
project with a simple structure. In the end, your project will use DigitalOcean
to deploy an Ubuntu 20.04 server (Droplet), install an Apache web server, and
point your domain to it.
10.
Building and Executing Selenium Project
Test
automation requires the creation and execution of Selenium projects. It
facilitates the execution of tests, the analysis of reports, and the reporting
of bugs.
Needless
to say, this aids in the faster delivery of high-quality products to clients,
making them happier. You will be able to demonstrate how to develop a Selenium
project employing both a “Java Project” and a “Maven Project” after completing
this project.
DevOps
Projects: Why Are They So Important?
Studying
devops is an essential skill to learn in order to make the software development
lifecycle more efficient. You are recommended to make some good DevOps projects
as DevOps engineers must be familiar with the below mentioned skills:
- Fundamentals
of Linux and Scripting:
Many firms prefer to host their apps on the Linux operating system,
therefore DevOps engineers must be familiar with it. In addition, Linux is
used to control the master nodes of configuration management systems like
Chef, Ansible, and Puppet.
- Continuous
Integration and Continuous Delivery: Continuous delivery (CD) is a computerized method
in which every update is designed, tested, and released automatically. On
the other hand, continuous integration (CI) is a procedure that requires
all members of a team to utilise a single version control system and to
integrate their work into the main branch on a frequent basis.
- Infrastructure
as Code:
With the rise of containerization and cloud computing technologies, the
infrastructure required by developers can now be given by an automated
script. The script is used to manage configurations and to run
configuration management software. It also runs the necessary commands. As
a result, the core application infrastructure or platform is available in
a matter of seconds.
- Configuration
Management:
The process of keeping track of software and operating system
configurations is known as configuration management. It can be used to
manage the configurations of thousands of servers by utilising the
management server to run a single command. Popular configuration
management software tools include Ansible, Chef, and Puppet.
- Automation: In DevOps, automation is a key
goal. It is the application of software to reduce human participation
while enhancing efficiency. Gradle, Git, Jenkins, and Docker are all
prominent automation platforms that DevOps engineers should be familiar
with.
Conclusion
DevOps
is a culture-shifting strategy that has and continues to benefit a wide range
of enterprises and organizations. Because of the growing demand for DevOps
skills, becoming a DevOps engineer provides several advantages.
DevOps
creates a seamless route for Continuous Development and Continuous Integration,
bridging the gap between the conflict of goals and priorities of developers and
operations team.
DevOps
is a vast discipline that has become one of the most in-demand technological
skills in recent years. This blog should hopefully serve as a starting point
for your journey into the realm of DevOps.
FAQs
Q.1:
How do you explain the DevOps project?
Ans: One of the greatest ways to explain any project in a large
topic like DevOps is to build things, rather than watching YouTube tutorials or
following step-by-step guidelines.
In
other words, analyze the problem statement in-depth, start finding the most
optimal solution and implement it, and you’ll learn without even recognizing
it. This knowledge will assist you in landing a great DevOps engineer role.
Working
on your own DevOps projects will teach you how to:
- Read
Documentation and Online Resources
- Research
on new and trending technologies
- Find and
contribute to online tech communities
- Troubleshoot
various issues while building the project
- Learn
various concepts and DevOps principles used in the project.
You
should describe projects that you have successfully accomplished in the past
during a DevOps interview. The goal is to demonstrate to the hiring manager the
breadth of your knowledge and experience with DevOps.
Q.2:
What is the main goal of DevOps?
Ans: DevOps’ main purpose is to tightly integrate automation and
monitoring at every stage of the software development life cycle (SDLC), from
integration to testing to release, deployment, and infrastructure
management.
Shortening
development cycles, increasing deployment frequency, and improving quality with
predictable releases are all goals of DevOps, which are all aligned with
business goals.
DevOps’
sole purpose is to remove the challenges from the software development
methodology and make it a more streamlined process in the following ways:
- Frequent
Software Releases:
New versions of the programme with the latest bug fixes and feature
additions are delivered more regularly due to an iterative development
approach, efficient peer code reviews, autonomous testing and build
pipelines, and continuous deployments. Manual processes and time-consuming
code reviews are avoided with automation at each stage of the DevOps
lifecycle, eliminating time delays.
- Internal
Communication:
DevOps plays a critical role in resolving communication and priority
issues between a company’s developer and operations teams. In the DevOps
methodology, the line between the two groups is exceedingly fine. DevOps
encourages better communication between teams, ensuring that everyone on
the technical team is aware of any changes made to the codebase, resulting
in more efficient incident management. These production adjustments are
minor, making them easily reversible in the event of a system failure.
- Relevance
to market dynamics:
DevOps focuses on harnessing the feedback of end-users and stakeholders in
an iterative software development process with more frequent releases. As
a result, the software can adapt to changing market conditions and remain
relevant to end-users.
Q.3:
What are the benefits of DevOps?
Ans: From a technology perspective, DevOps has a plethora of
advantages. Some of the benefits of DevOps are described below:
- DevOps
reduces the distinction between intra-organization teams (most notably,
developer and operations teams), resulting in fewer silos and improved
team communication.
- The
DevOps technique is intended for frequent app releases, resulting in a
shorter time-to-market.
- The
foundations of the DevOps application development process are feedback
loops. The application is always being improved in a rapid, iterative
manner based on feedback from users and internal stakeholders.
- Better
application monitoring and maintenance typically result in fewer
application downtimes, which means more consistent performance for users.
- One of
the pillars of the DevOps lifecycle is automation. It reduces manual
labour while also improving the overall reliability and consistency of the
application development pipeline.
- In
development, DevOps encourages increasing responsibility and code
ownership. The positions are typically broader and more adaptable.
- Finally,
automation and pipelining allow for a more efficient development process.

The Reasons Behind XAMPP MySQL Error
Running into this XAMPP MySQL Error “MySQL shutdown unexpectedly”
could be due to a bunch of reasons:
Port conflicts: MySQL uses 3306 by default. If
another computer application is using this port, MySQL won’t start, leading to
the shutdown.
Damaged tables or data files: If
the MySQL files become damaged – due to disk issues, unexpected shutdowns, or
other reasons – MySQL might not be able to start.
Inadequate configuration: Misconfigurations in your my.ini file, such as incorrect buffer
sizes or memory allocations, can cause startup failures.
Permissions issues: MySQL needs certain permissions
to access its data files and perform operations. If these permissions are
incorrect, MySQL’s operations could stop.

Thanks. Seems to work. Is it
going to be a problem later on, that I have two installations of the same
MySql? I wonder if it is not better to simply remove now stand alone MySql and
install xampp again?

A problem? Not really... more
of an annoyance. I think you should remove one or the other to be safe. All of
the standard mySQL interfaces are going to default to port 3306, as is the PHP code unless you
specify otherwise.

Fixing the XAMPP Error “MySQL Shutdown
Unexpectedly”
We got to the awaited troubleshooting part. Here’s a step-by-step
guide on how to fix the XAMPP error: “MySQL shutdown unexpectedly”
1. Check for Port Conflicts
For Windows Users:
1.
Open Command Prompt: Press
Win + R → type cmd → hit Enter.
2.
Use netstat: Type netstat -ano |
findstr 3306 → press Enter. This command searches for any applications using
port 3306, the default port for MySQL.
3.
Interpret the Output: If
you see a line of output, something is using port 3306. Note the PID
(Process ID) at the end of the line, as you’ll need it to identify the
conflicting application.
For macOS/Linux Users:
1.
Open Terminal.
2.
Use lsof: Type lsof -i :3306 → hit
Enter. This command lists open files and the corresponding applications using
port 3306.
3.
Read the Results: If
the command returns information, it means port 3306 is in use. Note the
application name or PID provided.
Having identified an application using port 3306, solve the issue
by changing the conflicted application’s port or the MySQL port.
Option 1: Use the PID or application name you noted earlier to
find the conflicting application. Find the configuration settings or file for
the application. Look for the port number setting (which should be set to 3306)
and change it to a different port number. Save your changes.
Option 2: Change MySQL’s Port in XAMPP: Open the my.ini file
located in your XAMPP MySQL folder, look for the line that specifies the port
(usually port=3306), and change it to a free port. Restart MySQL after making
this change.
2. Repair corrupted tables or data files
As we learned there might be corrupted MySQL tables or data files
within XAMPP causing the MySQL shutdown unexpectedly issue. Here are the steps
to identify the corruption.
1.
Go to your XAMPP installation directory → go to the mysql\data
folder. This is where MySQL stores database files.
2.
Look for any .err files, which are error log files
that might contain information about what went wrong.
3.
Review the files named after your databases. Pay attention to file
sizes and modification dates that seem out of the ordinary, as these can be
indicators of corruption.
If you have identified a corrupted file. Here is how to resolve
it.
For MyISAM tables
1.
Backup your data first.
Do this
through XAMPP’s phpMyAdmin by exporting your databases, or by using the mysqldump command
if you’re comfortable with command-line tools.
2.
Open your command prompt (Windows) or terminal (macOS/Linux).
Go to the bin folder inside your XAMPP’s MySQL directory by typing
cd followed by the path, like C:\xampp\mysql\bin for Windows
users.
In the command line, type myisamchk -r
/path/to/your/table.MYI, making sure to replace /path/to/your/table.MYI with
the real path to the MyISAM table you need to fix. The -r
stands for “recover,” aiming to repair your table.
Handling InnoDB Tables
InnoDB tables are a bit trickier due to their design, and there’s
no straightforward tool like myisamchk for them.
1.
Look at the .err files inside the mysql\data directory for error
messages about InnoDB tables. These can give you hints about what’s
wrong.
2.
Try a forced recovery. Force MySQL into a recovery mode. Edit
the my.ini (Windows) or my.cnf (other OS) file,
add innodb_force_recovery = 1 under the [mysqld] section,
and then restart MySQL.
If things look bad, your best bet might be to restore from a
backup. Hopefully, you have a recent one that can replace the damaged tables or
database.
3. Review and adjust configuration
1.
Open the my.ini file with a text editor. Key
things to review include the innodb_buffer_pool_size (increasing
it may help performance) and the paths specified in basedir and datadir.
2.
If you find any misconfigurations or suspect a setting could be
causing issues, make the necessary adjustments. For example, if innodb_buffer_pool_size is
set too low for your workload, increase it accordingly. Always backup the
original my.ini file before making changes.
4. Set correct permissions
MySQL or XAMPP might not have the necessary permissions to access
their directories and files, especially after updates or changes in security
software.
1.
Check the permissions of the MySQL and XAMPP folders.
2.
Ensure that the user account running XAMPP has full access rights.
3.
On Windows, you might need to right-click the XAMPP folder,
go to Properties → Security, and adjust accordingly.
4.
On macOS and Linux, use chmod and chown commands
to set the correct permissions.
5. Restart and monitor
After implementing the fixes, restart XAMPP and specifically the
MySQL service through the XAMPP Control Panel.
Keep an eye on the MySQL error log file for any new warnings or
errors. This log is usually found in the data directory or specified within
the my.ini file.
Summing up
When using local server environments, bumping into XAMPP MySQL
error, “MySQL shutdown unexpectedly” is a common issue you should know about.
It’s even critical to know how to fix it and get the server back up. In this
guide, we walked you through the basics of XAMPP, how it works, learned about
the issue, why it occurs, and how you can solve it step-by-step without
panicking.
If you’re using the local XAMPP server, keep this guide in reach
in case you encounter the issue again. Don’t worry, we’ve covered the whole
troubleshooting process in detail for you.
