PHP Array


An array is a single variable which can store multiple values at a time. Thus, PHP array is used to hold many values under a single name. These values can be accessed the by referring to their index number.

Syntax:

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

Types of Array:

PHP supports three types of array. These are:

  • Indexed arrays
  • Associative arrays
  • Multidimensional arrays

Advantages of using Array in PHP:

  • Single variable need to be declared, instead of multiple variable, making the code user friendly.
  • Less number of lines needed in a code.
  • Traversing of all the elements is easy.
  • Functions like sorting can be easily applied to all the elements.

Example 1: Using elements of an array.

<!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: Counting the number of elements in an array.

<!DOCTYPE html>
<html>
<body>
 
<?php
$food = array("PIZZA", "BURGER", "COKE");
echo count($food);
?>
 
</body>
</html>

Output
