Slicing a multi-dimensional PHP array across one of its elements

Question

Say for example you just queried a database and you recieved this 2D array.

$results = array(
    array(\'id\' => 1, \'name\' => \'red\'  , \'spin\' =&         


        

Answer 1

This is fast function alternative of array_column()

if(!function_exists('array_column')) {
    function array_column($element_name) {
        $ele =   array_map(function($element) {
            return $element[$element_name];
        }, $a);
        return  $ele;
    }
}
