XAMPP is a widely-used cross-platform web server that provides users with an integrated development environment (IDE) for building and testing web applications. It bundles all the necessary software components required for web development including Apache, PHP, and MySQL.
However, sometimes users may encounter compatibility issues when they try to run certain web applications on XAMPP, especially when they have newer versions of PHP installed on their system. In this scenario, the best solution is to downgrade PHP on XAMPP to a lower or stable version that is compatible with the web application you’re trying to run.
This article will guide you through the process of downgrading PHP on XAMPP and provide you with code examples to help you along the way.
Step 1: Download PHP archive file
The first step in downgrading PHP on XAMPP is to download the PHP archive file from the PHP website. You can download the specific version of PHP that is compatible with your web application.
For example, if you need to downgrade from PHP 8 to PHP 7.4, visit the PHP archives page and download the PHP 7.4 archive file.
Step 2: Extract the PHP archive file
After downloading the PHP archive file, you need to extract it into the XAMPP PHP directory.
By default, the XAMPP PHP directory is located at: C:\xampp\php. You should extract the contents of the downloaded file into this directory.
Step 3: Configure php.ini and httpd-xampp.conf files
The next step in downgrading PHP on XAMPP is to reconfigure the php.ini and httpd-xampp.conf files to use the downgraded version of PHP.
To do this, you need to open these files with a text editor (e.g., Notepad++) and make the necessary changes.
In the php.ini file, search for the line that reads “extension=php_xdebug.dll” (without the quotes) and comment it out by adding a semicolon (;) at the beginning of the line.
Next, scroll down to the line that reads “extension_dir = “C:\xampp\php\ext” (without the quotes) and make sure that the path points to the downgraded PHP version that you have extracted in step 2.
In the httpd-xampp.conf file, find the following lines:
LoadModule php_module “C:/xampp/php/php8apache2_4.dll”
AddHandler application/x-httpd-php .php
And replace them with:
LoadModule php_module “C:/xampp/php/php7apache2_4.dll”
AddHandler application/x-httpd-php .php
Step 4: Restart XAMPP web server
After making changes to the php.ini and httpd-xampp.conf files, you need to restart the XAMPP web server for the changes to take effect.
To do this, open the XAMPP control panel and click on the “Stop” button next to Apache. Wait for a few seconds and then click on the “Start” button to restart the web server.
Step 5: Test downgraded PHP version
Finally, you need to test the downgraded PHP version to make sure that everything is functioning as expected.
To do this, create a PHP file (e.g., test.php) with the following code:
Save the file in the XAMPP htdocs directory (e.g., C:\xampp\htdocs\test) and then open your web browser and type the following URL in the address bar:
http://localhost/test/test.php
If everything is configured correctly, you should see a page with information about the PHP version you have downgraded to.
In conclusion, downgrading PHP on XAMPP is a straightforward process that requires following a few simple steps. By following the steps outlined in this article, you should be able to downgrade PHP on XAMPP and run all the web applications you need.
Sure! Let me expand on some of the topics mentioned in the article.
XAMPP
XAMPP is a popular open-source cross-platform web server that is widely used by developers for web application development and testing. It contains all the necessary software components required for web development, including Apache, PHP, and MySQL. It can be installed on any operating system and is relatively simple to set up.
XAMPP provides users with an easy-to-use interface that allows them to manage their web server, start or stop Apache and MySQL, and configure settings. It also contains pre-configured modules for popular web applications like WordPress, Drupal, and Joomla, making it easy for developers to set up a development environment quickly.
The XAMPP community provides regular updates to the software to ensure that users have access to the latest technologies. However, it sometimes happens that newer versions of PHP or other components can break compatibility with legacy applications, which is why downgrading PHP on XAMPP may become necessary.
PHP
PHP is a popular server-side scripting language used for web development. It is known for its flexibility and ease of use, making it a favorite among developers. It is often used in combination with other web development technologies like HTML5, CSS, and JavaScript to create dynamic and interactive web applications.
PHP is regularly updated to introduce new features and improvements, but sometimes, these updates can cause compatibility issues with web applications developed using older versions of PHP. In such cases, the best solution is to downgrade PHP to a stable version that is compatible with the application.
PHP archives
PHP archives contain different versions of PHP, making them an excellent resource for developers who need to work with specific versions of PHP that have been tested and verified to work with specific web applications. The PHP archives are publicly available on the PHP website, making it easy for developers to locate and download the archive of the PHP version they need.
Code examples
Code examples are an essential part of any programming guide or tutorial as they provide users with a real-world context for the concepts being discussed. Code examples are designed to be illustrative and easy to understand, making it easier for developers to implement the concepts on their own.
In the article, code examples were used to demonstrate how to downgrade PHP on XAMPP. The code was presented alongside clear and concise instructions, making it easy for readers to follow along and implement the steps.
