PHP Manual: Pushes values onto the stack

public void Ds\Stack::push(mixed ...$values)

Pushes values onto the stack.

No value is returned.

Example #1 Ds\Stack::push example

<?php
$stack = new \Ds\Stack();

$stack->push("a");
$stack->push("b");
$stack->push("c", "d");
$stack->push(...["e", "f"]);

print_r($stack);
?>

The above example will output something similar to:

Ds\Stack Object
(
    [0] => a
    [1] => b
    [2] => c
    [3] => d
    [4] => e
    [5] => f
)
