How can I call a PHP function with some of the values from an array?

Question

Given the function bar takes a variable number of arguments. How can foo be implemented?

function foo($a, $b, $c) {
    return bar($a, $b, $c[0], $c[1], $c[2], ..., $c[n]);
}

Yeah, it seems like homework, plus there must be a duplicate question regarding PHP and variable number of function arguments — Dexygen

It's not homework. When I ask questions I remove everything that might confuse the matter. — AnnanFay

call_user_func_array allows you to call a function with an array of parameters. Create the parameter array and call the function:

$parameters = array_merge(array($a, $b), $c);
return call_user_func_array('bar', $parameters);
