Doesn't PHP have that already? http://us2.php.net/func_get_args http://us2.php.net/func_get_args
Edit - Checking out that parent link it seems:
Currently variadic functions are implemented by fetching the function arguments using func_get_args(). The following code sample shows an implementation of a variadic function used to prepare and execute a MySQL query (I'll be making use of this example throughout the RFC):
Firstly, by just looking at the function signature public function query($query) you cannot know that this is actually a variadic function. You'd think that the function can only run a normal query and doesn't support bound parameters:
public function query($query, ...$params) { /*...
$userData = $db->query('SELECT * FROM users WHERE id = ?', $userID)->fetch();
- TazeTSchnitzel 13y agoThere's a counterpart unpacking syntax which will likely also get merged in, meaning you can have: function query($query, ...$params) {} and $params = [3]; query('SELECT * FROM table WHERE a = ?;', ...$params);
