title: PHP max_input_vars
body: <p>I'm getting a <code>max_input_vars</code> error message. </p>
  
  <p>I understand there's a <code>php.ini</code> setting that can change this starting with version 5.3.9 however, I'm running version 5.1.6. </p>
  
  <p>When I view the configuration information for my 5.1.6 server it shows <code>max_input_vars</code> value is 1000. </p>
  
  <p>My question is: Even though I'm running 5.1.6, I see this setting from <code>phpinfo()</code> but it's not in the <code>php.ini</code> file. Does this mean that the value is hard coded in this version of PHP and can't be changed?</p>
