Splitting Arrays into Chunks with array_chunk()

<?php

$data = range('a', 'z'); // Create an array from 'a' to 'z'

// Split the array into chunks of 5 elements
$chunks = array_chunk($data, 5);
print_r($chunks);

echo "
";

$items = [
    'apple' => 1,
    'banana' => 2,
    'cherry' => 3,
    'date' => 4,
    'elderberry' => 5,
];

// Split preserving keys
$chunksPreservingKeys = array_chunk($items, 2, true);
print_r($chunksPreservingKeys);

?>

How it works: The `array_chunk()` function breaks an array into smaller arrays (chunks) of a specified size. This is particularly useful for tasks like displaying results in pages, processing items in batches, or creating sub-groups from a larger dataset already loaded into memory. The optional `preserve_keys` parameter allows you to maintain the original array keys within each chunk.
