note 76779 added to function.array-reduce

--REPOST, fixed some typos, please replace previous note-- In PHP ver. 4.3.1 the initial value parameter allowed for string type also. In PHP ver. 5.1.6 this param is now converted to int and callback function will receive number 0 when initial param is an empty string. <?php function arc ($reduced, $item) { $reduced = $item.$reduced; return $reduced; } array_reduce( array(a,b,c), "arc", "" ); ?> Output in PHP 4.3.1: cba Output in PHP 5.1.6: cba0 Possible solution: <?php function arc ($reduced, $item) { if ($reduced === 0) $reduced = ""; $reduced = $item.$reduced; return $reduced; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 86.61.77.143 ---- Manual Page -- http://www.php.net/manual/en/function.array-reduce.php Edit -- https://master.php.net/note/edit/76779 Del: integrated -- https://master.php.net/note/delete/76779/integrated Del: useless -- https://master.php.net/note/delete/76779/useless Del: bad code -- https://master.php.net/note/delete/76779/bad+code Del: spam -- https://master.php.net/note/delete/76779/spam Del: non-english -- https://master.php.net/note/delete/76779/non-english Del: in docs -- https://master.php.net/note/delete/76779/in+docs Del: other reasons-- https://master.php.net/note/delete/76779 Reject -- https://master.php.net/note/reject/76779 Search -- https://master.php.net/manage/user-notes.php
