How to usearray_map with range in PHP
You can use array_map with range to generate chunk indexes based on the array size and chunk size. Then, apply array_slice to extract chunks using these indexes, resulting in the array split into specific-sized chunks.
Example: This PHP script defines a custom_array_chunk function to split an array $arr into chunks of size 4 using array_map, range, and array_slice, displaying the result with print_r.
<?php
// Custom function to split array into chunks
function custom_array_chunk($array, $chunk_size) {
// Calculate the number of chunks needed
$num_chunks = ceil(count($array) / $chunk_size);
// Use array_map with range to create chunks
return array_map(function($i) use ($array, $chunk_size) {
// Calculate start index of current chunk
$start = $i * $chunk_size;
// Return slice of array for current chunk
return array_slice($array, $start, $chunk_size);
}, range(0, $num_chunks - 1));
}
// Declare an array
$arr = [
"G", "e", "e", "k", "s",
"f", "o", "r", "G", "e",
"e", "k", "s"
];
// Split array into chunks of size 4 using custom function
$result = custom_array_chunk($arr, 4);
// Print the result
print_r($result);
?>
Output
Array
(
[0] => Array
(
[0] => G
[1] => e
[2] => e
[3] => k
)
[1] => Array
(
[0] => s
[1] => f
