note 47921 added to function.shm-get-var

if the variable_key asked for does not exist php generates a warning and shm_get_var() will return bool(false). there doesn't seem to be a clean way to test if a key exists. ---- Manual Page -- http://www.php.net/manual/en/function.shm-get-var.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47921 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47921&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47921&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47921&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47921&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47921&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47921&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47921&report=yes Search -- http://master.php.net/manage/user-notes.php
