array_chunk
(PHP 4 >= 4.2.0)
array_chunk -- Split an array into chunks
Description
array
array_chunk ( array input, int size [, bool preserve_keys])
array_chunk() splits the array into
several arrays with size values
in them. You may also have an array with less values
at the end. You get the arrays as members of a
multidimensional array indexed with numbers starting
from zero.
By setting the optional preserve_keys
parameter to TRUE, you can force PHP to preserve the original
keys from the input array. If you specify FALSE new number
indices will be used in each resulting array with
indices starting from zero. The default is FALSE.
Example 1. array_chunk() example <?php
$input_array = array('a', 'b', 'c', 'd', 'e');
print_r(array_chunk($input_array, 2));
print_r(array_chunk($input_array, 2, TRUE));
?> |
The printout of the above program will be:
