The splat operator was introduced in PHP starting with version 5.6, so, to can use it and test the examples from this page, you need PHP 5.6+.
The Splat Operator is represented by three dots (...), and can be used to define functions that can be called with a variable number of arguments.
<?php function add($a, $b, $c) { return $a + $b + $c; } $arguments = [8, 9]; // array with values for $b and $c parameters echo add(5, ...$arguments); // 22 ?>2. The splat operator can also be used when the function is defined, before a parameter that represents an array of arguments.
<?php // $params is an array containing the remaining arguments function add($opt = 0, ...$params) { $sum = $opt + array_sum($params); echo '$opt is '. $opt .' / $params contains '. count($params .' arguments / $sum = '. $sum; } add(); // $opt is 0 / $params contains 0 arguments / $sum = 0 add(1); // $opt is 1 / $params contains 0 arguments / $sum = 1 add(5, 6); // $opt is 5 / $params contains 1 arguments / $sum = 11 add(5, 6, 7); // $opt is 5 / $params contains 2 arguments / $sum = 18 add(5, 6, 7, 8); // $opt is 5 / $params contains 3 arguments / $sum = 26 ?>
