Passing variable argument list to sprintf()

Question

I would like to write a function that (amongst other things) accepts a variable number of arguments and then passes them to sprintf().

For example:

<?php
function some_func($var) {
  // ...
  $s = sprintf($var, ...arguments that were passed...);
  // ...
}

some_func("blah %d blah", $number);
?>

How do I do this in PHP?

Answer 1

Or better yet (and a bit safer too):

function some_func(string $fmt, ... $args) {
    $s = vsprintf($fmt, $args);
}

This is PHP 7.4, not sure if it works in earlier versions.
