For some reason, the following php script when called via apache, is not returning results... is there a system security setting in php.ini somewhere to allow system commands?

```
<div style="background:#000;color:#fff">
<?php

   $cmd = "/bin/date";
   $output = system($cmd);
   printf("System Output: $output\n");
   exec($cmd, $results);
   printf("Exec Output: {$results[0]}\n");
   echo"<pre>";
   echo system('/bin/ls');
   echo"</pre>";
   ?>
   </div>

```
