ID: 55773 User updated by: Ray dot Paseur at Gmail dot com Reported by: Ray dot Paseur at Gmail dot com Summary: foreach issues warning with function main() Status: Bogus Type: Bug Package: SimpleXML related Operating System: Linux PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: Thanks for your comment. I have two questions before I abandon this line of thinking. First, what would you recommend to accomplish the removal of a child from an object based on an attribute of the child? And second, why would a warning pointing to the nonexistent function main() in the line number of foreach() be considered "expected" behavior? The php.net web site tells us to report a bug if we get a message identifying function main(). You can look it up. http://php.net/manual/en/function.main.php Surely if this is an error in foreach() an error message might be crafted that gave a hint about the problem, eh? Feel free to contact me offline if you have questions about what I posted in the report. I'll be glad to try to clarify or help in any way.

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 You're removing a child from the object whilst in the middle of iterating over it. At that point, all bets are off, really. I'm happy enough to call that expected behaviour, because I don't think there's actually anything sensible that can be done. ------------------------------------------------------------------------ [2011-09-24 01:32:02] Ray dot Paseur at Gmail dot com Description: ------------ http://www.laprbass.com/RAY_xml_delete_nodes.php Outputs: Warning: main() [function.main]: Node no longer exists in /home/websitet/public_html/RAY_xml_delete_nodes.php on line 12 <?xml version="1.0"?> <category id="1" title="category 1"> <item id="b" title="item b" delete="false"/> </category> Test script: --------------- <?php // RAY_xml_delete_nodes.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' /> </category> XML; $obj = SimpleXML_Load_string($xml); $key = 0; foreach ($obj as $item) { if ($item["delete"] == 'true') unset($obj->item[$key]); $key++; } $new = $obj->asXML(); echo htmlentities($new); Expected result: ---------------- No warning message.
