How to Split an Array in PHP ?

Answer

To split an array in PHP, you can use the array_chunk function or array_slice function.

✐ Examples

1 Splitting an Array using array_chunk Function

In this example,

We create an array named $numbers with integer elements.
We then use the array_chunk function to split $numbers into chunks of a specified size.
The array_chunk function returns an array of chunks.

PHP Program

<?php
$numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
$chunks = array_chunk($numbers, 3);
print_r($chunks);
?>

Output

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

    [1] => Array
        (
            [0] => 4
            [1] => 5
            [2] => 6
        )

    [2] => Array
        (
            [0] => 7
            [1] => 8
            [2] => 9
        )

)

2 Splitting an Array using array_slice Function

In this example,

We create an array named $numbers with integer elements.
We then use the array_slice function to extract a slice of $numbers based on indices.
The array_slice function returns an array representing the sliced elements.

PHP Program

<?php
$numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
$slice1 = array_slice($numbers, 0, 3);
$slice2 = array_slice($numbers, 3, 3);
$slice3 = array_slice($numbers, 6, 3);
print_r([$slice1, $slice2, $slice3]);
?>

Output

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

    [1] => Array
        (
            [0] => 4
            [1] => 5
            [2] => 6
        )

    [2] => Array
        (
            [0] => 7
            [1] => 8
            [2] => 9
        )

)
