Syntax of array_chunk
array array_chunk(array array, int size[, int preserve_keys])
Splits array into a series of arrays, each containing size elements, and returns them in an array. If preserve_keys is true (default is false), the original keys are preserved in the resulting arrays; otherwise, the values are ordered with numeric indices starting at 0
Example of array_chunk
<?php
$input_array = array('a', 'b', 'c', 'd', 'e');
print_r(array_chunk($input_array, 2));
print_r(array_chunk($input_array, 2, true));
?>
Output
Array ( [0] => Array ( [0] => a [1] => b ) [1] => Array ( [0] => c [1] => d ) [2] => Array ( [0] => e ) ) Array ( [0] => Array ( [0] => a [1] => b ) [1] => Array ( [2] => c [3] => d ) [2] => Array ( [4] => e ) )
