title: setting max_input_vars PHP.ini directive using ini_set
body: <p>Can I set the max_input_vars PHP.ini directive in my code? I have it set at the default 1000, however I have a script that has many checkboxes and text fields that could, and quite possibly will, go over the 1000 limit.</p>
  
  <p>I'm using PHP 5.3.10 and i'm not getting any errors doing this. Also, I can't find any documentation that states I can't do this.</p>
  
  <pre><code>ini_set('max_input_vars', 3000);
  </code></pre>
  
  <p>Thanks.</p>
