How to pass array as multiple parameters to function?

I want to create a function with a variable number of parameters in PHP, kinda like a souped up version of sprintf. E.g. Where sprintf might look like this:

$res = sprintf("The number is %d and the string is %s", $num, $str);

with an arbitrary number of arguments, I want to do something like this:

function my_special_printf($special, $format, ....lots of args...)
{
    // do something with $special here

    return sprintf($format, .. lots of args...);
}

Is this possible?

Use func_get_args();

http://php.net/manual/en/function.func-get-args.php

This function returns all the parameters in array.

<?php
function my_printf() {
   $args = func_get_args();
   $string = &args[0];
   return call_user_func_array('printf', $args);
}
?>

or:

<?php
function my_printf($string) {
   $args = func_get_args();
   $args = array_shift($args);
   return vsprintf($string, $args);
}
?>
