How to rename array keys in PHP?

Question

When I var_dump on a variable called $tags (a multidimensional array) I get this:

Array
(
    [0] => Array
        (
            [name] => tabbing
            [url         


        

Answer 1

Talking about functional PHP, I have this more generic answer:

    array_map(function($arr){
        $ret = $arr;
        $ret['value'] = $ret['url'];
        unset($ret['url']);
        return $ret;
    }, $tag);
}
