note 17304 added to function.array-walk

TIP: Any function to be used with array_walk() should expect arguments representing a value, a key and optionally a further argument. EXAMPLE: // the function function printit( $stuff, $key, $a_arg = 0) { print $stuff." = not an argument $key = top level key<br>\n"; if( $a_arg != 0 && is_array($a_arg) ) { foreach( $a_arg as $key2=>$val ) { print $val." = argument & $key2 = 2nd level key & $key = top level key<br>\n"; } } print "done<br>\n"; } // the array & optional arguments $the_array = array("Item 1","Item2","Item3"); $args = array("argument1","argument2,"argument3"); // the call to array_walk array_walk($the_array,"printit",$args); /* or since I have made the arguments optional...it could just simply be: array_walk($the_array,"printit"); */ -- http://www.php.net/manual/en/function.array-walk.php http://master.php.net/manage/user-notes.php?action=edit+17304 http://master.php.net/manage/user-notes.php?action=delete+17304 http://master.php.net/manage/user-notes.php?action=reject+17304
