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 ) );

?>

PHP array_chunk() function

The PHP array_chunk() method is a sophisticated array manipulation tool that divides an array into smaller, more manageable pieces. Whether you’re dealing with a huge dataset or just want to arrange your data, this function makes it simple to split an array into different sections, giving you greater flexibility over how you interact with it. Whether you want to boost speed or simply make your code more legible and manageable, this method provides a simple yet effective array manipulation solution.

What is the syntax of the array_chunk function in PHP?

array array_chunk ( array $input , int $size [, bool $preserve_keys = false ] )

Parameter	Details
array	Required. Array to split into chunks
size	Required (integer). Set the size of each chunk
preserve_key	This is an Optional parameter. Preserves the keys when set to true Reindexes the chunk numerically when set to false

Array_chunk function in PHP

The array_chunk() function returns an multidimensional array, containing the chunks as arrays.

Examples of the array_chunk function

$fruits = array("Apple", "Banana", "Cherry", "date", "Elderberry", "Fig", "Grape", "Honeydew"); $chunks = array_chunk($fruits, 2); print_r($chunks);

In this example, we’ll make a variety of fruits. The array_chunk() method is then used to divide it into 2 parts. The resultant array will be a multidimensional array with four subarrays, the first of which will have two items, the second of which will have two elements, and so on.

$numbers = array(1, 2, 3, 4, 5, 6, 7, 8); $chunks = array_chunk($numbers, 3, true); print_r($chunks);

In this example, we’ll make a number array. Then we divide it into three chunks with the array_chunk() method and set the third option to true to keep the keys. The resultant array will be a multidimensional array with three subarrays, the first of which will have three items, the second of which will have three elements, and so on, with the keys intact.

$employee = array("Name" => "John Doe", "Age" => 30, "Salary" => 5000, "Designation" => "Developer"); $chunks = array_chunk($employee, 2, true); print_r($chunks);

In this example, we’ll make an associative array containing employee information. The array_chunk() method is then used to divide it into chunks of two, and the third parameter is set to true to preserve the keys. The resultant array will be a multidimensional array with two subarrays; the first will have two items, the second will have two elements, and the keys will be kept.

It’s vital to notice that the array_chunk() method returns a new array containing the updated chunks rather than modifying the old array.

It’s also worth noting that if the total number of elements in the array is greater than the chunk size, the last chunk will have less elements than the others.

For more information see the official reference.
