note 48746 added to function.unset

I saw this mentioned somewhere else but if you do $var = NULL then I've noticed memory actually being freed up, not 100% though. Where as with unset($var), no memory is freed. This might be useful if you're doing a php-gtk app, thats starting to consume significant memory over a long period of time. ---- Manual Page -- http://www.php.net/manual/en/function.unset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48746 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48746&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48746&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48746&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48746&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48746&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48746&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48746&report=yes Search -- http://master.php.net/manage/user-notes.php
