Accessing array elements

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