note 59104 added to language.references.unset

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 ?> I haven't test this trick a lot, but well, it seems to work greatly. ---- Manual Page -- http://www.php.net/manual/en/language.references.unset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59104 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59104&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59104&report=yes Search -- http://master.php.net/manage/user-notes.php
