An array is a collection of values with different data types
An array can be created using the array() language construct. It takes any number of comma-separated key => value pairs as arguments.
Syntax:
array(
key => value,
key2 => value2,
key3 => value3,

// as of PHP 5.4
<?php
$array = array(

"bar" => "foo",
);
$array = [

“bar” => “foo”,
];
?>
