PHP Multidimensional Arrays

Multidimensional arrays in PHP are arrays that contain other arrays as elements.

Example of PHP Multidimensional Arrays

<?php
$person = array(
    "name" => "John",
    "age" => 30,
    "address" => array(
        "street" => "123 Main St",
        "city" => "New York",
        "state" => "NY"
    )
);

echo $person['name'] . "\n";
// Outputs: John
echo $person['age'] . "\n";
// Outputs: 30
echo $person['address']['street'] . "\n";
// Outputs: 123 Main St
echo $person['address']['city'] . "\n";
// Outputs: New York
echo $person['address']['state'] . "\n";
// Outputs: NY
?>

Output:

John
30
123 Main St
New York
NY

Explanation: This example demonstrates the use of multidimensional arrays in PHP. The array is defined with three elements, and the third element is another array that contains three elements.
