Description:
------------
Foreach issues warning with link to http://php.net/manual/en/function.main.php when iterating over SimpleXML object.

Test script:
---------------
<?php // oop_bug_main.php
error_reporting(E_ALL);
echo "<pre>";
$xml = <<<XML
<category id='1' title='category 1'>
  <item id='a' title='item a' delete='true' />
  <item id='b' title='item b' delete='false'>B Stays</item>
</category>
XML;
$obj = SimpleXML_Load_string($xml);
$key = 0;
foreach ($obj->item as $item) {
    $attrs = $item->attributes();
    if ($attrs['delete'] == 'true') unset($obj->item[$key]);
    $key++;
}

Expected result:
----------------
No message about function main()

Actual result:
--------------
<pre><br />
<b>Warning</b>:  main() [<a href='function.main'>function.main</a>]: Node no longer exists in <b>/Applications/MAMP/htdocs/oop_bug_main.php</b> on line <b>12</b><br />

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

this main means it's at the top scope...

"this main means it's at the top scope..."  

What does that mean, in plain language, please?  The script fails, and it issues a warning message that refers the client to a page that says, "If you discover such a reference, please ยป file a bug report, indicating the PHP function caused the error that linked to main() and it will be fixed and properly documented."

I'd be grateful for your help, thanks.
