Accessing array elements with square bracket syntax

Array elements can be accessed using the array[key] syntax.

Example #7 Accessing array elements

<?php
$array = array(
    "foo" => "bar",
    42    => 24,
    "multi" => array(
         "dimensional" => array(
             "array" => "foo"
         )
    )
);
var_dump($array["foo"]);var_dump($array[42]);var_dump($array["multi"]["dimensional"]["array"]);?>

The above example will output:

string(3) "bar"
int(24)
string(3) "foo"

As of PHP 5.4 it is possible to array dereference the result of a function or method call directly. Before it was only possible using a temporary variable.
