when to use array_chunk with examples ? in php

The array_chunk() function in PHP is used to split an array into chunks of smaller arrays. This can be useful when you want to process a large array in smaller parts, or when you want to display data in a paginated manner.

Here's an example to illustrate how to use array_chunk():


main.php
// Original array
$data = array('apple', 'banana', 'cherry', 'date', 'elderberry', 'fig', 'grape', 'honeydew', 'kiwi');

// Split the original array into chunks of 3 elements each
$chunks = array_chunk($data, 3);

// Output each chunk
foreach ($chunks as $chunk) {
    print_r($chunk);
}
288 chars
11 lines

In this example, the original array will be split into chunks of 3 elements each. The output will be:


main.php
Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
)
Array
(
    [0] => date
    [1] => elderberry
    [2] => fig
)
Array
(
    [0] => grape
    [1] => honeydew
    [2] => kiwi
)
189 chars
19 lines

This can be particularly useful when you want to paginate results or when you need to process large datasets in smaller, manageable parts.
