title: Where does PHP get its settings if no configuration file is loaded?
body: <p>I have set up PHP 5.3.10 on a RHEL 4 server.</p>
  
  <p>When I ran <code>php -i | grep "Loaded"</code> it returned</p>
  
  <p><code>Loaded Configuration File =&gt; (none)</code></p>
  
  <p>It's OK with that setup. PHP is working the way we needed it to. I just need to know, if no php.ini is being used, where does PHP get all its settings? Thanks.</p>
  
  <p>Update: I realized this after I hit submit. Sorry, how do I move this to Stack Overflow? -_-</p>
  
  <p>Update 2: Result of <code>php --ini</code>:</p>
  
  <p><code>Configuration File (php.ini) Path: /usr/local/lib
  Loaded Configuration File:         (none)
  Scan for additional .ini files in: (none)
  Additional .ini files parsed:      (none)</code></p>
