How to pass a string with a few comma separated values as function parameters

问题

For instance:

$str = '1, 2, 4, 13';

I'd like the effect to be as if it were:

func(1, 2, 4, 13)

回答1:

$params = explode(', ', $str);
call_user_func_array("func", $params);

回答2:

$str = '1, 2, 4, 13';
function func($one, $two, $three, $four) {
    var_dump(func_get_args());
}
call_user_func_array('func', explode(', ', $str));

Remember, you can pass as many parameters to a function and accessing them with func_get_args(), they dont have to be defined in the methods signature.
