title: php timeout - set_time_limit(0); - don't work
body: <p>I'm having a problem with my PHP file that takes more than 30 seconds to execute.</p>
  
  <p>After searching, I added <code>set_time_limit(0);</code> at the start of the code,cbut the file still times out with a <code>500 error</code> after 30 seconds.</p>
  
  <pre><code>log: PHP Fatal error:  Maximum execution time of 30 seconds exceeded in /xxx/xx/xxx.php
  
  safe-mode : off
