Status = SUSPENDED TO PHP USERS: *ONLY* change parameter passed! *Never* change array or array elements in walk funciton. ------------------------------------------------------------------------ [2002-01-27 05:19:57] sander@php.net No feedback. ------------------------------------------------------------------------ [2002-01-06 07:37:36] sander@php.net Does this problem still occur with 4.1.1? ------------------------------------------------------------------------ [2001-08-16 17:25:58] rasmus@php.net On my machine, this will crash it: function test($val,$key) { global $globalArray; $globalArray[]=$key; } $arr=array('k'=>'v'); array_walk($arr,'test'); echo "testing".$globalArray[0]; Changing the last line to: echo "test".$globalArray[0]; makes it work.
