array_partition

Опис

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”.

Наприклад:

$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.

Встановлення

  1. Install via the built-in WordPress plugin installer. Or download and unzip array-partition.zip inside the plugins directory for your site (typically wp-content/plugins/)
  2. Activate the plugin through the ‘Plugins’ admin menu in WordPress
  3. Use the c2c_array_partition() function in your template(s) or code as desired.

Часті питання

Why not use PHP’s built-in `array_chunk()`?

array_chunk() allows you to specify the number of elements per partition, not how many partitions you want. (See Description.).

For an array with 12 elements, if you requested a chunk size of 2, you would get back an array of 6 sub-arrays (the original elements grouped into arrays of 2 elements). With array_partition(), if you requested 2 partitions, you would get back an array of 2 sub-arrays (the original elements grouped into 2 arrays).

Phrased another way, with array_chunk() you tell it how many elements max should be in a partition and it gives you as many partitions as necessary. With c2c_array_partition(), you tell it how many partitions you want, and it’ll evenly split the elements into those partitions as evenly as possible.

Does this plugin include unit tests?

Yes.
