array_partition
This plugin provides the PHP function c2c_array_partition() to split an array into any number of sub-arrays, suitable for creating evenly distributed, vertically filled “columns”. Also known as “chunking” or “partitioning”.
例如：
$topics = array( "aardvark", "bear", "cat", "dog", "emu", "fox", "gnu", "hippo", "ibis", "jackal" );
print_r( c2c_array_partition( $topics, 4 ) );
Yields:
Array
(
[0] => Array
(
[0] => ant
[1] => bear
[2] => cat
)
[1] => Array
(
[0] => dog
[1] => emu
[2] => fox
)
[2] => Array
(
[0] => gnu
[1] => hippo
)
[3] => Array
(
[0] => ibis
[1] => jackal
)
)
Note the array elements are distributed into the requested 4 “columns” as evenly as possible.
The function will fill as many partitions as requested, as long as there are enough elements in the array to do so. Any remaining unfilled partitions will be represented as empty arrays.
In contrast, using PHP’s built-in array_chunk() as such:
print_r( array_chunk( $topics, 4 ) );
Yields:
Array
(
[0] => Array
(
[0] => aardvark
[1] => bear
[2] => cat
[3] => dog
)
[1] => Array
(
[0] => emu
[1] => fox
[2] => gnu
[3] => hippo
)
[2] => Array
(
[0] => ibis
[1] => jackal
)
)
It can be sent an array of any data types or objects.
