note 46969 added to function.ob-start

I wanted to do things a very particular way with output buffering and shutdown functions; using register_shutdown_function instead of the built in callback feature of this function. However, one should note that this won't work, because the contents of the buffer are no longer in scope when PHP is calling the shutdown functions. This would have been easy to see EXCEPT that PHP graciously flushes any unsent buffers at the end of the script, or when calling exit. So: <?php ob_start(); echo 'hi'; exit; ?> Prints "hi". In a nutshell, if you want it to have a shutdown function that handles an output buffer, just specify it in ob_start() and let PHP automatically call it at the end of the script. ---- Manual Page -- http://www.php.net/manual/en/function.ob-start.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46969 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46969&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+46969&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+46969&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+46969&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+46969&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+46969&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+46969&report=yes Search -- http://master.php.net/manage/user-notes.php
