Cannot increase memory_limit with ini_set()
<p>I just noticed that I am unable to increase my memory limit above the value configured in php.ini using <a href="http://php.net/manual/en/function.ini-set.php"><code>ini_set()</code></a>. I can, however, set it to any value below that and increase it to any other value below the one defined in the ini-file.</p>

<p>Does anyone know why this happens or how I could fix it?</p>
