title: Set ini max_execution_time doesn't work
body: <p>Before I use nginx and php-fpm, I used Apache, so when I wanted only one of my cron jobs to run without time execution limitation, I used these lines in my PHP code:</p>
  
  <pre><code>set_time_limit(0);
  ini_set('max_execution_time', 0); 
  </code></pre>
  
  <p>but after I migrated from Apache to nginx, this code doesn't work. I know ways to change <code>nginx.conf</code> to increase maximum execution time.</p>
  
  <p>But I want to handle this with php code. Is there a way?
  I want to specify only one file that can run PHP code without time limitation.</p>
