array_chunk
Chunks an array into arrays with length elements. The last chunk may contain less than length elements.
Parameters
When set to true keys will be preserved. Default is false which will reindex the chunk numerically
Return Values
Returns a multidimensional numerically indexed array, starting with zero, with each dimension containing length elements.
Errors/Exceptions
If length is less than 1 , a ValueError will be thrown.
Changelog
| Version | Description |
|---|---|
| 8.0.0 | If length is less than 1 , a ValueError will be thrown now; previously, an error of level E_WARNING has been raised instead, and the function returned null . |
Examples
Example #1 array_chunk() example
$input_array = array( ‘a’ , ‘b’ , ‘c’ , ‘d’ , ‘e’ );
print_r ( array_chunk ( $input_array , 2 ));
print_r ( array_chunk ( $input_array , 2 , true ));
?>
The above example will 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 ) )

Tried to use an example below (#56022) for array_chunk_fixed that would «partition» or divide an array into a desired number of split lists — a useful procedure for «chunking» up objects or text items into columns, or partitioning any type of data resource. However, there seems to be a flaw with array_chunk_fixed — for instance, try it with a nine item list and with four partitions. It results in 3 entries with 3 items, then a blank array.
So, here is the output of my own dabbling on the matter:
function partition ( $list , $p ) $listlen = count ( $list );
$partlen = floor ( $listlen / $p );
$partrem = $listlen % $p ;
$partition = array();
$mark = 0 ;
for ( $px = 0 ; $px < $p ; $px ++) $incr = ( $px < $partrem ) ? $partlen + 1 : $partlen ;
$partition [ $px ] = array_slice ( $list , $mark , $incr );
$mark += $incr ;
>
return $partition ;

$citylist = array( «Black Canyon City» , «Chandler» , «Flagstaff» , «Gilbert» , «Glendale» , «Globe» , «Mesa» , «Miami» ,
«Phoenix» , «Peoria» , «Prescott» , «Scottsdale» , «Sun City» , «Surprise» , «Tempe» , «Tucson» , «Wickenburg» );
print_r ( partition ( $citylist , 3 ) );
?>

array_chunk
Разбивает массив на массивы с элементами length . Последний блок может содержать элементы меньше length .
Parameters
Если установлено значение true , ключи будут сохранены. По умолчанию false , что приведет к переиндексации чанка численно.
Return Values
Возвращает многомерный массив с числовым индексом, начиная с нуля, причем каждое измерение содержит элементы length .
Errors/Exceptions
Если length меньше 1, будет E_WARNING и возвращено значение null .
Examples
Пример # 1 array_chunk () Пример
$input_array = array('a', 'b', 'c', 'd', 'e'); print_r(array_chunk($input_array, 2)); print_r(array_chunk($input_array, 2, true)); ?> Выводится приведенный выше пример:
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 ) )
