title: Get max_execution_time in PHP script
body: <p>I know it is possible to set the maximum execution time in a script using either:</p>
  
  <pre><code>ini_set('max_execution_time', 30);
  </code></pre>
  
  <p>or</p>
  
  <pre><code>set_time_limit(30);
  </code></pre>
  
  <p>What can I do to get a variable containing the maximum execution time in seconds?</p>
