Plesk gives you the ability to enable or disable specific PHP
extensions, and also to manually configure a wide range of PHP settings.
These settings can be configured for every PHP version independently of
all others (for example, you can set up a list of enabled extensions for
PHP 5.3 that is entirely different to that of PHP 5.4) and are applied
to every PHP handler type (for example, if you enable the xdebug
extension for PHP 5.3, it will be enabled for all domains using PHP 5.3,
whether they use CGI, FastCGI, or PHP-FPM handler).
To change the PHP settings for an individual PHP version, go to Tools
& Settings > PHP Settings and click the name of any of the PHP
version + handler type combinations whose PHP version matches that whose
settings you want to change. For example, if you want to change settings
for PHP 5.3, you can click either 5.3.3 Apache module or 5.3.3
FastCGI application. You can manage the following PHP settings here:
- Enable or disable PHP extensions from a predefined list.
- Configure the desired PHP settings by editing the
php.inifile.
Any changes you make will be in effect for all websites using that PHP
version. Note that customers who have the permission to manage PHP
settings are able to configure certain PHP settings for their domains
and subdomains. Settings they configure on the domain level will
override server-wide settings.
