If from a function I am returned a multidimensional array like this..
array(0 => array('a' => 5), 1 => array('a' => 8))
But I just really need the contents of the key 'a' what is the best way for me to convert.
Current I have been doing something like..
$new_array = array();
foreach ($multi_array AS $row) {
$new_array[] = $row['a']
}
