note 56994 added to function.isset

Based on the previous post, I've found this code even more useful: <?php function isset_sum(&$var, $val) { if (isset($var)) $var += $val; else $var = $val; } ?> Now instead of: <?php if (isset($foo[$bar][$baz][$fooz])) $foo[$bar][$baz][$fooz] += $count; else $foo[$bar][$baz][$fooz] = $count; ?> No more "Undefined variable" warnings, and you save your fingers and sanity! Thanks to the previous poster for inspiration. ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56994 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56994&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56994&report=yes Search -- http://master.php.net/manage/user-notes.php
