title: using shell_exec to call a perl script from php
body: <p>I am having an issue with executing a perl script from php using the shell_exec() function.</p>
  
  <p>This is what I have tried (and it has worked before).</p>
  
  <pre><code>$perl = shell_exec("/usr/bin/perl cbh_script_clean.pl");
  echo ($perl);
  </code></pre>
  
  <p>This will not work as $perl does not contain anything after this is executed.</p>
  
  <p>Thoughts?</p>
  
  <p>All help is appreciated!</p>
  
  <p>Thanks.</p>
