106<h2 id="php.ini">php.ini</h2>
107<p>PHP settings are defined in:</p>
108<ul>
109<li>a main configuration file, usually found under <code>/etc/php5/php.ini</code>; some distributions provide different configuration environments, e.g.
110<ul>
111<li><code>/etc/php5/php.ini</code> - used when running console scripts</li>
112<li><code>/etc/php5/apache2/php.ini</code> - used when a client requests PHP resources from Apache</li>
113<li><code>/etc/php5/php-fpm.conf</code> - used when PHP requests are proxied to PHP-FPM</li>
114</ul></li>
115<li>additional configuration files/entries, depending on the installed/enabled extensions:
116<ul>
117<li><code>/etc/php/conf.d/xdebug.ini</code></li>
118</ul></li>

128<ul>
129<li>create a <code>phpinfo.php</code> script located in a path supported by the web server, e.g.

132<li><code>/var/www/test/phpinfo.php</code></li>
133</ul></li>
134<li>make sure the script is readable by the web server user/group (usually, <code>www</code>, <code>www-data</code> or <code>httpd</code>)</li>
135<li>access the script from a web browser</li>
136<li><p>look at the <em>Loaded Configuration File</em> and <em>Scan this dir for additional .ini files</em> entries</p>
