if that is the case & should appear before all the other variables as well....
and.....
<?php
function foo(&$val, $key) {
if(is_numeric($value)) {
$value = $value + 0;
}
}
$_POST = array( '1', '100', '100.1', '100.123', 'a');
array_walk_recursive($_POST, 'foo');
var_dump($_POST);
?>
is giving me
array(5) { [0]=> int(1) [1]=> int(100) [2]=> float(100.1) [3]=>
float(100.123) [4]=> string(1) "a" }
ny idea y this difference arises?
