php function 'pcntl_exec' is undefined
<p>Would anyone know why my <code>pcntl_exec</code> is undefined?  I have php 5.2.14 - the <a href="http://php.net/manual/en/function.pcntl-exec.php" rel="nofollow">manual</a> says it should be defined in php5.  I need an alternative to exec as my hosting provider recently  locked-down these: exec, passthru, shell_exec, system, proc_open, popen, curl_multi_exec</p>

<p>I got the list from: <code>ini_get("disable_functions")</code>.  I see no reason for it to be undefined.</p>
