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

You could use array_map() to do it.

$tags = array_map(function($tag) {
    return array(
        'name' => $tag['name'],
        'value' => $tag['url']
    );
}, $tags);
