How to Initialize an Array in PHP ?

To initialize an array in PHP, you can use array() or square brackets.

In this example,

We initialize an array named numbers using the array() function with integer values.
This creates an array of integers in PHP.
We print the array elements using print_r().

<?php
$numbers = array(1, 2, 3, 4, 5);
print_r($numbers);
?>

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)

In this example,

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

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