How to Declare an Array in PHP - Step by Step Examples

How to Declare an Array in PHP ?

To declare an array in PHP, you use the array() function or the [] shorthand notation.

In this example,

We declare an array named fruits using the array() function and initialize it with some values.
This creates an array in PHP.
We print the array elements using print_r().

<?php
$fruits = array('Apple', 'Banana', 'Orange');
print_r($fruits);
?>

Array
(
    [0] => Apple
    [1] => Banana
    [2] => Orange
)

In this example,

We declare an associative array named person with key-value pairs using the [] shorthand notation.
We print the array elements using print_r().

<?php
$person = ['name' => 'Alice', 'age' => 30, 'city' => 'New York'];
print_r($person);
?>

Array
(
    [name] => Alice
    [age] => 30
