note 61039 added to language.references.unset

clerca at inp-net dot eu dot org " If you have a lot of references linked to the same contents, maybe it could be useful to do this : <?php $a = 1; $b = & $a; $c = & $b; // $a, $b, $c reference the same content '1' $b = NULL; // All variables $a, $b or $c are unset ?> " ------------------------ NULL will not result in unseting the variables. Its only change the value to "null" for all the variables. becouse they all points to the same "part" in the memory. ---- Server IP: 192.117.122.43 Probable Submitter: 81.218.104.136 ---- Manual Page -- http://www.php.net/manual/en/language.references.unset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+61039 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+61039&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+61039&report=yes Search -- http://master.php.net/manage/user-notes.php
