Splitting an array into another multi-array

Splitting an array into another multi-array

Hi guys,
Lets say that I have an array with 11 elements
like the diagram of the array below:

$full_array = array(
['1'] => 'abc',
['2'] => 'cde',
['3'] => 'ghf',
['4'] => '12g',
['5'] => 'gh5',
['6'] => '878',
['7'] => '14y',
['8'] => 'd56',
['9'] => 'hj6',
['10'] => '9h7',
['11'] => 'o89'
);

now with the array above I would like to now
split it up and store it in another array,
"an array of arrays"
but there should be "no more than 3 elements"
in each array (sub-array) when it's split up,
example below:

$split_array = array(

[0] => array(['1'] => 'abc',
['2'] => 'cde',
['3'] => 'ghf')

[1] => array(['4'] => '12g',
['5'] => 'gh5',
['6'] => '878')

[2] => array(['7'] => '14y',
['8'] => 'd56',
['9'] => 'hj6')

[3] => array(['10'] => '9h7',
['11'] => 'o89')

);

What is the easiest wway to accomplish the above
task.

An example would be nice!

Thank you!

PHP Code:


		
			
for (j = 0; $j < size($full_array) / 3; $j + 3) {

    $index = 0;

    for ($i = $j; $i < $j + 3; $i++) {

        $split_array[$index][$i] = $full_array[$i];

    }

    $index++;

}



print_r($split_array);

I haven't tested this code, so there might be an off-by-one error, but the logic should be correct.
