note 61649 added to function.ini-set

To slightly improve on Tree2054's code, there is no need to use isset() to check if $$rg_var is initialised, because if register_globals is On then every key present in one of the superglobal arrays the code uses will definitely have been initialised as a variable by that name. ---- Server IP: 85.116.0.130 Probable Submitter: 62.254.128.4 (proxied: 86.3.137.152) ---- Manual Page -- http://www.php.net/manual/en/function.ini-set.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+61649 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+61649&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+61649&report=yes Search -- http://master.php.net/manage/user-notes.php
