note 79526 added to function.key

What's the point of lines 14 and 25? $array is destroyed when the function returns. If you want this to work as written, change line 2 to this: (pass $array by reference instead of by value) <? function add_key ($value, &$array) // returns the key of the value added or existing already within the array ?> > danny at dannymendel dot com > 12-Apr-2006 09:41 > An auto incremental key value function, returning the key value: > > 1 <? > 2 function add_key ($value, $array) // returns the key of the value added or existing > already within the array > 3 { > 4 if (is_array ($array)) > 5 { > 6 if (!in_array ($value, $array)) > 7 { > 8 ksort ($array); > 9 >10 end ($array); >11 >12 $key = key ($array) + 1; >13 >14 $array[$key] = $value; >15 } >16 else >17 { >18 $key = array_search ($value, $array); >19 } >20 } >21 else >22 { >23 $key = 1; >24 >25 $array[$key] = $value; >26 } >27 return $key; >28 } >29 ?> ---- Server IP: 209.41.74.194 Probable Submitter: 207.224.195.213 ---- Manual Page -- http://www.php.net/manual/en/function.key.php Edit -- https://master.php.net/note/edit/79526 Del: integrated -- https://master.php.net/note/delete/79526/integrated Del: useless -- https://master.php.net/note/delete/79526/useless Del: bad code -- https://master.php.net/note/delete/79526/bad+code Del: spam -- https://master.php.net/note/delete/79526/spam Del: non-english -- https://master.php.net/note/delete/79526/non-english Del: in docs -- https://master.php.net/note/delete/79526/in+docs Del: other reasons-- https://master.php.net/note/delete/79526 Reject -- https://master.php.net/note/reject/79526 Search -- https://master.php.net/manage/user-notes.php
