106 | <p>PHP settings are defined in:</p> | |
107 | <ul> | |
108 | <li>a main configuration file, usually found under <code>/etc/php5/php.ini</code>; some distributions provide different configuration environments, e.g. | |
109 | <ul> | |
110 | <li><code>/etc/php5/php.ini</code> - used when running console scripts</li> | |
111 | <li><code>/etc/php5/apache2/php.ini</code> - used when a client requests PHP resources from Apache</li> | |
112 | <li><code>/etc/php5/php-fpm.conf</code> - used when PHP requests are proxied to PHP-FPM</li> | |
113 | </ul></li> | |
114 | <li>additional configuration files/entries, depending on the installed/enabled extensions: | |
