PHP array_​chunk Function

array_​chunk() is an another PHP prebuilt / default array function, This function is basically allows user split an array into smaller chunks of new array or we can say if we need to create smaller array of a big array then we can use the array_chunk();

Syntax of array_​chunk() :

array_chunk(array, length, preserve_key)

array (required) : It is the array for which we need to make the chunks or smaller array.
length (required) : The size of each chunk
preserve_key (optional) : true – Preserves the keys false – default. Reindexes the chunk numerically

Return Type / Values :
it returns a multidimensional numerically indexed array, starting with zero, with each dimension containing length elements.

Example 1 :

<?php
	$input_array = array('Rolex', 'Omega', 'Orpat', 'Tuder', 'Panerai');
	print_r(array_chunk($input_array, 2));
	print_r(array_chunk($input_array, 2, true));
?>

Output will be :

Array 
( 
	[0] => Array 
		( 
			[0] => Rolex 
			[1] => Omega ) 

	[1] => Array 
		( 
			[0] => Orpat 
			[1] => Tuder 
		) 

	[2] => Array 
	( 
		[0] => Panerai 
	) 
)

Array 
	( 
		[0] => Array 
			( 
				[0] => Rolex 
				[1] => Omega 
			) 
		[1] => Array 
			( 
				[2] => Orpat 
				[3] => Tuder 
			) 
		[2] => Array 
			( 
				[4] => Panerai 
			) 
	)

Example 2 :

<?php
	$actual_age = array("Monu"=>"23","Sonu"=>"25","Parth"=>"10","Kanav"=>"4");
	print_r(array_chunk($actual_age, 2, true));
?>

Output will be:

Array 
	( 
		[0] => Array 
			( 
				[Monu] => 23 
				[Sonu] => 25 
			) 
		[1] => Array
