Example #1 Ds\Vector::contains() example

<?php
$vector = new \Ds\Vector(['a', 'b', 'c', 1, 2, 3]);

var_dump($vector->contains('a'));                // true
var_dump($vector->contains('a', 'b'));           // true
var_dump($vector->contains('c', 'd'));           // false

var_dump($vector->contains(...['c', 'b', 'a'])); // true

// Always strict
var_dump($vector->contains(1));                  // true
var_dump($vector->contains('1'));                // false

var_dump($vector->contains(...[]));                // true
?>
