note 104018 added to function.array-walk-recursive

Guys, If you intend to use Rob's recursive function to extract the last key value of an array, don't forget to insert a currency sign ($) signal before "$output" at 7th line. This value must be a variable, and if you forgot to assign this signal, your code won't work, displaying an error like this: Parse error: syntax error, unexpected ')', expecting T_PAAMAYIM_NEKUDOTAYIM in /home/ffilho/www/temp/arraywalk.php on line 7 I've lost several minutes until discovery this. Hope this info be useful for someone. ---- Server IP: 187.16.23.128 Probable Submitter: 200.144.115.82 ---- Manual Page -- http://www.php.net/manual/en/function.array-walk-recursive.php Edit -- https://master.php.net/note/edit/104018 Del: integrated -- https://master.php.net/note/delete/104018/integrated Del: useless -- https://master.php.net/note/delete/104018/useless Del: bad code -- https://master.php.net/note/delete/104018/bad+code Del: spam -- https://master.php.net/note/delete/104018/spam Del: non-english -- https://master.php.net/note/delete/104018/non-english Del: in docs -- https://master.php.net/note/delete/104018/in+docs Del: other reasons-- https://master.php.net/note/delete/104018 Reject -- https://master.php.net/note/reject/104018 Search -- https://master.php.net/manage/user-notes.php
