note 50300 added to function.microtime

Interesting quirk (tested in PHP 5.0.3): You can get very wacky results from microtime when it is called in the destructor of an object at the end of a script. These times vary enormously and can be in the *past*, when compared to microtime calls in the body of the script. As a case example, I played with a timer object that measured microtime when it was created at the start of the script, and measured microtime again at the end of the script using __destruct(); and then printed the total execution time (end time - start time) at the bottom of the page. On short scripts, this would often give a negative time! This quirk does not appear if microtime is measured with an automatic shutdown function (using <?PHP register_shutdown_function('myfunc') ?>. Incidentally, the automatic shutdown functions are called after output buffers are flushed but before object destructors are called. ---- Manual Page -- http://www.php.net/manual/en/function.microtime.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50300 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50300&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50300&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50300&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50300&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50300&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50300&report=yes Search -- http://master.php.net/manage/user-notes.php
