In this post, we’ll talk about Arrays in PHP.

What is an Array?

An array stores multiple values in one single variable. An array is a special variable, which can hold more than one value at a time. If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this:

$cars1 = "Volvo";
$cars2 = "BMW";
$cars3 = "Toyota";

In PHP, there are three types of arrays:

• Indexed arrays – Arrays with a numeric index
• Associative arrays – Arrays with named keys
• Multidimensional arrays – Arrays containing one or more arrays

Example 1: Multidimensional Array.

<?php 
	$data = array
	( 
		array("Ram", "Shyam", "Love"), 
		array("Delhi", "Mumbai", "Kanpur") 
	); 
	
	echo "<pre>";
	print_r($data);
	echo "</pre>";
?>

Output

Array
(
    [0] => Array
        (
            [0] => Ram
            [1] => Shyam
            [2] => Love
        )

    [1] => Array
        (
            [0] => Delhi
            [1] => Mumbai
            [2] => Kanpur
        )

)

Example 2: Array of PHP Objects

<?php 
class Car
{
    public $color;
    public $type;
}

$myCar = new Car();

$myCar->color = 'red';
$myCar->type = 'sedan';

$yourCar = new Car();

$yourCar->color = 'blue';
$yourCar->type = 'suv';

$pmCar = new Car();

$pmCar->color = 'White';
$pmCar->type = 'BMW';

$cars = array($myCar, $yourCar , $pmCar);

foreach ($cars as $car) {
    echo 'This car is a ' . $car->color . ' ' . $car->type . "\n";
}
?>
