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

Starting PHP 5.3, you can use this pretty call with lambda function:

$names = array_map(function ($v){ return $v['name']; }, $results);

This will return array sliced by 'name' dimension.
