1. Configure handlers for different versions and point them to already provided php-cgi binaries, they all are visible from CageFS inside. Add the following section to [handlers] section in /opt/suphp/etc/suphp.conf :
application/x-httpd-php52="php:/opt/alt/php52/usr/bin/php-cgi"
2. Add suPHP handlers for each version, this should be done before other configs. On cPanel server, edit /usr/local/apache/conf/includes/pre_virtualhost_global.conf and add the following section:
<IfModule mod_suphp.c>
3. Restart Apache.
That’s it, now Apache understands what binary should be used for different mime types. To use desired version in a particular directory, just add a line to .htaccess in that directory (or create .htaccess file with that line, if it is not there).
For example, for php5.4, add the following line:
AddHandler application/x-httpd-php54.php.php5
Subdirectories will use the same PHP version as the parent, unless you override it with another .htaccess entry in that subdirectory.
