Writing to XML

Okay… Basically I’m trying to write to an XML file with updated information.

But my fwrite() function keeps returning the following error:

Warning: fwrite(): supplied argument is not a valid stream resource in [file path/name] on line 122

So can anybody tell me why the following isn’t a valid string:

<?xml version="1.0"?>





<maintable><![CDATA[This is the text for the Main page.]]></maintable>

<subtable><![CDATA[This is subtable text for the Main page.]]></subtable>

<infotable><![CDATA[<p>Contemporary Service: 8:30am<br />(dress casual)</p><p>Sunday School and Adult Bible Study: 10:00am</p><p>Traditional Service: 11:00am</p><p>Evening Worship: 6:00pm</p>]]></infotable>

<pastortable><![CDATA[Please click on any of the links to the right to browse the website.]]></pastortable>
















It is a single line with
for line breaks, stored in a variable ($xmlOutput – isn’t it quaint) and then used in the fwrite() command as follows:

if (fwrite($xml_file, $xmlOutput) === FALSE) {
        die("Cannot write to file ($xml_file)");

What do you think? Am I missing some funky reserved character or something? I’ve looked all over but I’m not finding anything… I’d appreciate your help!
