Code example:

Now we need to split the array into An array block of two elements, retaining the key names from the original array.

<?php
$age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43","Harry"=>"50");
print_r(array_chunk($age,2,true));
?>

Output result:

Array
(
    [0] => Array
        (
            [Peter] => 35
            [Ben] => 37
        )

    [1] => Array
        (
            [Joe] => 43
            [Harry] => 50
        )

)
