Note Submitter: Fausto Filho ---- 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.
