$a = array (0 => 1, 1 => 2, 2 => 3);
$b = array (1 => 2, 2 => 3, 0 => 1);
var_dump($a == $b); // bool(true)
var_dump($a === $b); // bool(false)
`==` compares the variable from `$a with $b`<br>
`===` compares the same datatypes from `$a with $b`
$a = array (0 => 1, 1 => 2, 2 => 3);
$b = array (1 => 2, 2 => 3, 0 => 1);
$c = array (0 => 1, 1 => 2, 2 => 3);
var_dump( $a === $b ); // False
var_dump( $a === $c ); // True
The arrays must match, same order.
