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:
<informalexample>
<programlisting role="php">
<![CDATA[
<?php
error_reporting(E_ALL);
/* Add redirection so we can get stderr. */
$fp = popen('/path/to/spooge 2>&1', 'r');
echo "'$fp'; " . gettype($fp) . "\n";
$read = fread($fp, 2096);
echo $read;
pclose($fp);
?>
