PHP Indexed Array

PHP Array can be used to store number, string and object. The index of the array element is assigned automatically starting from 0 or can be assigned manually.

Syntax 1:

$arrayName = array(value 1, value 2, ...);

Syntax 2:

$arrayName[0] = "value 1";
$arrayName[1] = "value 2";
$arrayName[2] = "value 3";

Example 1: Using elements of an array by its index.

<!DOCTYPE html>
<html>
<body>
 
<?php
$food = array("PIZZA", "BURGER", "COKE");
echo "I love to eat " . $food[0] . ", " . $food[1] . " and " . $food[2] . ".";
?>
 
</body>
</html>

Output

I love to eat PIZZA, BURGER and COKE.

Example 2: Looping through the elements in an array.

<!DOCTYPE html>
<html>
<body>
 
<?php
$food = array("PIZZA", "BURGER", "COKE");
$arrlength = count($food);
 
 
for($x = 0; $x < $arrlength; $x++) {
	echo $food[$x];
	echo "<br>";
}
?>
</body>
</html>

Output

PIZZA
BURGER
COKE
