PHP get function arguments as array?

func_get_args() returns an array with all arguments of the current function.

<?php function sum($a,$b,$c,$d) {    $numbers = func_get_args();     $acc = 0;     foreach ($numbers as $n) {         $acc += $n;     }     return $acc; }   echo sum(1, 2, 3, 4); ?>

PHP5.6 – splat operator

Arrays and Traversable objects can be unpacked into argument lists when calling functions by using the … operator. This is also known as the splat operator in other languages.

<?php function sum(...$numbers) {     $acc = 0;     foreach ($numbers as $n) {         $acc += $n;     }     return $acc; }   echo sum(1, 2, 3, 4); ?>
