note 63104 added to function.register-shutdown-function

I have discovered a change in behavior from PHP 5.0.4 to PHP 5.1.2 when using a shutdown function in conjunction with an output buffering callback. In PHP 5.0.4 (and earlier versions I believe) the shutdown function is called after the output buffering callback. In PHP 5.1.2 (not sure when the change occurred) the shutdown function is called before the output buffering callback. Test code: <?php function ob_callback($buf) { $buf .= '<li>' . __FUNCTION__ .'</li>'; return $buf; } function shutdown_func() { echo '<li>' . __FUNCTION__ .'</li>'; } ob_start('ob_callback'); register_shutdown_function('shutdown_func'); echo '<ol>'; ?> PHP 5.0.4: 1. ob_callback 2. shutdown_func PHP 5.1.2: 1. shutdown_func 2. ob_callback ---- Server IP: 64.71.164.2 Probable Submitter: 207.190.225.90 ---- X-Spam-Status: No, hits=3.3 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER, HTML_MESSAGE autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.register-shutdown-function.php Edit -- http://master.php.net/note/edit/63104 Del: integrated -- http://master.php.net/note/delete/63104/integrated Del: useless -- http://master.php.net/note/delete/63104/useless Del: bad code -- http://master.php.net/note/delete/63104/bad+code Del: spam -- http://master.php.net/note/delete/63104/spam Del: non-english -- http://master.php.net/note/delete/63104/non-english Del: in docs -- http://master.php.net/note/delete/63104/in+docs Del: other reasons-- http://master.php.net/note/delete/63104 Reject -- http://master.php.net/note/reject/63104 Search -- http://master.php.net/manage/user-notes.php
