Not directly, but:
$post = array();
foreach($_POST as $k => $v){
$k = str_replace('_', ' ', $k);
$post[$k] = $v;
}
You could dink with unset instead, but it's a Bad Idea to alter what
is actually in $_POST, imho.
And you also don't really want to add new elements to an array while
you iterate through it, generally... Though I think maybe foreach
does the right thing with that.
Better to build a new array and put the stuff you want into that.
