title: PHP set_time_limit() does not work, safemode is off
body: <p>I try to disable the time limit in an PHP script by</p>
  
  <pre><code>set_time_limit(0);
  </code></pre>
  
  <p>but it does not work; the script is still aborted after the system default of 30 seconds. The <code>max_execution_time</code> setting - as displayed by <code>phpinfo()</code> after <code>set_time_limit(0)</code> - still shows 30 seconds for both Master and Local value. It also shows that Safe Mode is Off.</p>
  
  <p>Do you have any idea what goes wrong? It's PHP 5.3.3 <s>(cli)</s> running on CentOS 6.2 with Apache 2.2.15.</p>
