If the command to be executed could not be found, a valid
|
||||
resource is returned. This may seem odd, but makes sense; it
|
||||
allows you to access any error message returned by the shell:

|

<programlisting role="php">
|
||||
<![CDATA[

<?php

error_reporting(E_ALL);

/* Add redirection so we can get stderr. */
