PHP Variable Length Argument Function
PHP supports variable length argument function. It means you can pass 0, 1 or n number of arguments in function. To do so, you need to use 3 ellipses (dots) before the argument name.
The 3 dot concept is implemented for variable length argument since PHP 5.6.
Let's see a simple example of PHP variable length argument function.
- <?php
- function add(...$numbers) {
- $sum = 0;
- foreach ($numbers as $n) {
- $sum += $n;
- }
- return $sum;
- }
- echo add(1, 2, 3, 4);
- ?>
