title: How can I know which 'php.ini' file is used?
body: <p>I search the path where the <em>php.ini</em> file is located in our Linux Ubuntu server, and I found many <em>php.ini</em> files when executing the command <code>find / -name php.ini</code>. So how can I know exactly from a PHP script web page where the php.ini is located?</p>
