Apache 2.4 - Switch PHP versions through URL prefix

php-versions-through-url.conf

##########################################################################################################################
#
#  Define which version of PHP to run based on the URL, this allows to use different PHP versions on a same project
#  It also allows to use different projects with different PHP versions at the same time
#
#  Example 1:  https://localhost/php74/my-project will run on PHP 7.4
#              https://localhost/php82/my-project will run on PHP 8.2 even though the sources are in the same folder
#
#  Prerequisites:
#       - Apache 2.4+
#       - Several PHP versions already installed
#
#  Usage:
#       - Copy this file to your Apache conf folder
#           - On Unix it might be `/etc/apache2/conf-available`
#           - On Windows, for WampServer it should be `C:/wamp64/bin/apache/apache2.4.<X>.<Y>/conf/extra`
#       - Include this file the virtual hosts for which you want to enable this
#           - On Unix it might be `Include conf-available/php-versions-through-url.conf`
#           - On Windows, for WampServer it should be `Include conf/extra/php-versions-through-url.conf`
#       - Go the Unix / Windows section below, and follow the steps corresponding to your platform
#       - Restart Apache
#       - Access your project by prefixing the URL with the desired PHP version
#         (eg. for "https://localhost/my-project", type "https://localhost/php74/my-project" to run it on PHP 7.4)

# Uncomment to help debug the URL rewriting rule (output should be in error log)
#LogLevel rewrite:trace6

RewriteEngine On
# First, retrieve PHP version from the URL
SetEnvIf Request_URI "^/php([0-9])([0-9])/" URL_PHP_VERSION=$1.$2
# Then rewrite the URL to ignore it and use the regular URLs defined in virtual hosts
RewriteRule "^/php([0-9])([0-9])/(.*)$" /$3 [L]

# - Uncomment and adjust this line to the path of your PHPs
# - URL_PHP_VERSION will be like "8.2", if you need to change the format of this variable, check the `SetEnvIf` line above
#
#<FilesMatch \.php$>
#        SetHandler "proxy:unix:/var/run/php/php%{ENV:URL_PHP_VERSION}-fpm.sock|fcgi://localhost/"

## Step 1
# - Enable "proxy_module", "proxy_fcgi_module" and "setenvif_module" modules in Apache configuration
## Step 2
# - PHPROOT should already be defined in your Apache conf, if not uncomment the following line and put the abs. path to you PHP binaries up to the version number
#
#Define PHPROOT ${INSTALL_DIR}/bin/php/php
#
## Step 3
# - Uncomment and adjust these lines to the path and versions of your PHPs
# - URL_PHP_VERSION will be like "8.2", if you need to change the format of this variable, check the `SetEnvIf` line above
#
#<IfModule fcgid_module>
#    # Define which binary to use regarding the selected version
#    # - Default PHP version used if URL not starting with "/phpXY/"
#    FcgidWrapper "${PHPROOT}7.4.33/php-cgi.exe" .php
#    # - Available PHP versions
#    <If "%{ENV:URL_PHP_VERSION} == '5.6'">

#    # Define which php.ini file to use
#    #
#    # Note: Strangely when using the ${URL_PHP_VERSION} variable in the path, Apache doesn't start, but as this directive is mandatory
#    #       we pass a non existing file path so it will load its default php.ini.
