Suppress echo from PHP include file
<p>I have a file <code>PHP01.php</code> which: 
- performs a function
- creates an array
- echo's some message</p>

<p>I need to include this file in another php script, say <code>PHP02.php</code> as I need access to the array it created. But when I jquery POST request to <code>PHP02.php</code>, the data it returns also has the <code>echo</code> from <code>PHP01.php</code></p>

<p>How can I suppress the echo from the first file?</p>
