#32406 [Opn]: PHP claims that headers are set when __destruct is called

ID: 32406 Updated by: derick@php.net Reported By: webmaster at benliles dot com Status: Open -Bug Type: Zend Engine 2 problem +Bug Type: Documentation problem Operating System: * PHP Version: 5.* New Comment: Marcus is right, this is expected and should be documented if it's not already Previous Comments: ------------------------------------------------------------------------ [2005-03-22 01:04:07] webmaster at benliles dot com We are output buffering and in the destructor for a page class, we dump the output buffer. There is nothing in the documentation to indicate when headers would be sent before this point. Also, the headers_sent function is not reporting correct information. The file name is blank and line number is zero. ------------------------------------------------------------------------ [2005-03-22 00:19:27] helly@php.net 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 __destruct is called during script shut down - that is everything has already been sent. Add a '$test = NULL;' in front of the '?>' and you'll see. ------------------------------------------------------------------------ [2005-03-22 00:16:31] webmaster at benliles dot com Description: ------------ It appears that PHP has a flag set for headers already being sent when __destruct() is called despite the fact that nothing is being sent before that. This has been seen in PHP 5.0.2 and PHP 5.0.3 with two different operating systems. This is not documented as claimed in an earlier bug report. Reproduce code: --------------- <? class letsTestThis { public function __destruct() { if (!headers_sent($file,$line)) { header("Content-type: text/xml"); echo "Some cool XML!"; } else { echo "Headers already sent in file: ".$file."<BR>\nOn Line: ".$line."<BR>\n"; } } } $test = new letsTestThis(); ?> Expected result: ---------------- Some cool XML Actual result: -------------- Headers already sent in file: On Line: 0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32406&edit=1
