Juggling multiple PHP projects? It’s a common scenario for developers to need different PHP versions for various projects. Perhaps you’re maintaining a legacy application that relies on an older PHP version while simultaneously developing a cutting-edge project requiring the latest features. This begs the question: Can you run multiple PHP versions within a single XAMPP installation? The short answer is yes, with a few clever tweaks. This guide will walk you through the process of configuring your XAMPP environment to seamlessly switch between different PHP versions, saving you the hassle of managing separate installations.
Understanding the Challenge
XAMPP, by default, ships with a single PHP version. Attempting to run projects requiring different versions can lead to compatibility issues, errors, and ultimately, frustration. The solution lies in leveraging XAMPP’s flexibility and configuring it to recognize and utilize multiple PHP installations.
One common misconception is that you need to install multiple XAMPP instances. This is not only unnecessary but also resource-intensive. A more efficient approach involves installing the desired PHP versions and then configuring XAMPP to switch between them as needed. This streamlined approach saves disk space and simplifies the development process.
Installing Multiple PHP Versions
The first step is to acquire the desired PHP versions. You can download the binaries from the official PHP website (https://www.php.net/downloads.php). Choose the versions that match your project requirements, ensuring you download the appropriate thread-safe versions compatible with XAMPP’s Apache. Extract the downloaded archives to separate directories within your XAMPP installation, for example, xampp/php7.4 and xampp/php8.0.
Once extracted, you’ll need to configure each PHP version by copying the php.ini-development file to php.ini within each respective directory. This php.ini file acts as the configuration file for your PHP installation. You can then customize each php.ini according to your project needs.
Configuring XAMPP to Switch PHP Versions
Now comes the crucial part: configuring XAMPP’s Apache to recognize and utilize these different PHP versions. This involves modifying the Apache configuration file, httpd.conf. Open the file, typically located at xampp/apache/conf/httpd.conf, and locate the lines related to PHP module loading. You’ll need to comment out the existing PHP module loading line and add new lines for each PHP version.
- Comment out the existing PHP module loading line (e.g., LoadModule php7_module “C:/xampp/php/php7apache2_4.dll”).
- Add new lines for each PHP version. For example:
<IfModule alias_module> ScriptAlias /php7.4 "C:/xampp/php7.4" Action application/x-httpd-php7.4 "/php7.4/php-cgi.exe" AddHandler application/x-httpd-php7.4 .php </IfModule> <IfModule alias_module> ScriptAlias /php8.0 "C:/xampp/php8.0" Action application/x-httpd-php8.0 "/php8.0/php-cgi.exe" AddHandler application/x-httpd-php8.0 .php </IfModule>
Finally, to switch between PHP versions for different projects, use the .htaccess file within each project’s root directory. Add the following line to the .htaccess file, specifying the desired PHP version:
SetHandler application/x-httpd-php7.4 (or application/x-httpd-php8.0, etc.)
Testing Your Configuration
After making these changes, restart your Apache server. Create a simple phpinfo.php file in each project’s root directory. Accessing this file through your browser will display the currently active PHP version. This allows you to confirm that XAMPP is correctly utilizing the specified PHP version for each project.
By following these steps, you gain the flexibility to manage multiple projects with varying PHP requirements within a single XAMPP installation. This approach not only simplifies your development workflow but also conserves resources.
Troubleshooting
Occasionally, you might encounter issues during the configuration process. Common pitfalls include incorrect paths in the httpd.conf or .htaccess files. Ensure the paths accurately reflect the location of your PHP installations. Another potential issue is forgetting to restart Apache after making configuration changes. Always restart Apache for the changes to take effect.

Question & Answer :
We are running XAMPP with PHP 7.0 because our new products requires PHP 7.
But there are old projects which use functions like mysql_connect, etc. Those are removed in PHP 7.0.
So, is there a way to easily change PHP versions in XAMPP?
Note: Please don’t suggest to upgrade old project to compatible with new versions because I am not in a position to do it because of that decisions I can’t get as a developer (just an employee).
Why switch between PHP versions when you can use multiple PHP versions at the same time with a single xampp installation?
With a single xampp installation, you have 4 options:
- Run an older PHP version for only the directory of your old project: This will serve the purpose most of the time. You may have one or two old projects that you intend to run with an older PHP version. Just configure xampp to run an older PHP version for only those project directories.
- Run an older PHP version on a separate port of xampp: Sometimes you may be upgrading an old project to the latest PHP version and at the same time you need to run the same project back and forth between the new PHP version and the old PHP version. To do this you can set an older PHP version on a different port (say 8056) so when you go to
http://localhost/any_project/, xampp runs PHP 7 and when you go tohttp://localhost:8056/any_project/xampp runs PHP 5.6. - Run an older PHP version on a virtualhost: You can create a virtualhost like localhost56 to run PHP 5.6 while you can use PHP 7 on localhost.
Lets set it up
Step 1: Download PHP
So you have PHP 7 running under xampp, you want to add an older PHP version to it (say PHP 5.6). Download the nts (Non Thread Safe) version of the PHP zip archive from php.net (see archive for older versions) and extract the files under c:\xampp\php56. The thread safe version does not include php-cgi.exe.
Step 2: Configure php.ini
Open the file c:\xampp\php56\php.ini in notepad. If the file does not exist, copy php.ini-development to php.ini and open it in notepad. Then uncomment the following line:
extension_dir = "ext"
Also if the following line exists in Apache config httpd-xampp.conf
SetEnv PHPRC "\\path\\to\\xampp\\php"
comment it out with with a leading # (hash character).
Step 3: Configure apache
Open xampp control panel, click the config button for apache, and click Apache (httpd-xampp.conf). A text file will open. Put the following settings at the bottom of the file:
ScriptAlias /php56 "C:/xampp/php56" Action application/x-httpd-php56-cgi /php56/php-cgi.exe <Directory "C:/xampp/php56"> AllowOverride None Options None Require all denied <Files "php-cgi.exe"> Require all granted </Files> </Directory>
Note: You can add more versions of PHP to your xampp installation following step 1 to 3 if you want.
Step 4 (option 1): [Add Directories to run a specific PHP version]
Now you can set directories that will run in PHP 5.6. Just add the following at the bottom of the config file (httpd-xampp.conf from Step 3) to set directories.
<Directory "C:\xampp\htdocs\my_old_project1"> <FilesMatch "\.php$"> SetHandler application/x-httpd-php56-cgi </FilesMatch> </Directory> <Directory "C:\xampp\htdocs\my_old_project2"> <FilesMatch "\.php$"> SetHandler application/x-httpd-php56-cgi </FilesMatch> </Directory>
Step 4 (option 2): [Run an older PHP version on a separate port]
Now to to set PHP v5.6 on port 8056, add the following code to the bottom of the config file (httpd-xampp.conf from Step 3).
Listen 8056 <VirtualHost *:8056> <FilesMatch "\.php$"> SetHandler application/x-httpd-php56-cgi </FilesMatch> </VirtualHost>
Step 4 (option 3): [Run an older PHP version on a virtualhost]
To create a virtualhost (localhost56) on a directory (htdocs56) to use PHP v5.6 on http://localhost56, create directory htdocs56 at your desired location and add localhost56 to your hosts file (see how), then add the following code to the bottom of the config file (httpd-xampp.conf from Step 3).
<VirtualHost localhost56:80> DocumentRoot "C:\xampp\htdocs56" ServerName localhost56 <Directory "C:\xampp\htdocs56"> Require all granted </Directory> <FilesMatch "\.php$"> SetHandler application/x-httpd-php56-cgi </FilesMatch> </VirtualHost>
Finish: Save and Restart Apache
Save and close the config file. Restart apache from the xampp control panel. If you went for option 2, you can see the additional port(8056) listed in your xampp control panel.
