note 59292 added to function.sort

I had an array like this: $arr=array (1,4,3,6,5); which returns this: $arr[0]=1 $arr[1]=4 $arr[2]=3 $arr[3]=6 $arr[4]=5 But lets say i remove [2] which is number 3, i get: $arr[0]=1 $arr[1]=4 $arr[3]=6 $arr[4]=5 And i want to reindex without doing a sort because i dont want to lose the order of the numbers (like a pop in a stack but in the middle of the list), i do this: $arr=array_chunk($arr,count($arr)); $arr=$arr[0]; the result is: $arr[0]=1 $arr[1]=4 $arr[2]=6 $arr[3]=5 This can be applied mostly for tree sorting, when you only have the id and the parent values of the node, and you want to have N levels. ---- Manual Page -- http://www.php.net/manual/en/function.sort.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59292 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59292&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59292&report=yes Search -- http://master.php.net/manage/user-notes.php
