1.2.404. Ellipsis Usage¶
Usage of the ellipsis keyword. The keyword is three dots : ... . It is also named variadic or splat operator.
It may be in function definitions and function calls; it may be in arrays; it is also usable with parenthesis.
… allows for packing or unpacking arguments into an array.
<?php
$args = [1, 2, 3];
foo(...$args);
// Identical to foo(1,2,3);
function bar(...$a) {
// Identical to : $a = func_get_args();
}
?>
