Remove “columns” from the subarrays of a two dimensional array

Question

I have a simple, two dimensional array like this:

Array
    (
        [0] => Array
            (
                [0] => abc
                [1] => 1         


        

Answer 1

Even with array_walk :

array_walk(
    $aYourArray,
    function(&$aSubRow){
        $aSubRow = array_slice($aSubRow, 0, 2);
    }
);
