title: Changes in my php.ini are not reflected - "memory_limit" seems to get overridden by another file
body: <p>I'm on Mac OS X and I'm using PHP. I need to increase the memory_limit from 256M to 1024M. However, when I modify the value in the <em>php.ini</em> file, the changes do not get reflected.</p>
  <p>Normally, I think my <em>php.ini</em> file is located in</p>
  <pre><code>/usr/local/php5/lib/php.ini
  </code></pre>
  <p>as mentioned on my <em>phpInfo.php</em> page. Other values get updated, but not this one. Therefore, it seems that <em>memory_limit</em> gets overwritten by another file. Is there a way to determine where it gets overwritten?</p>
