How to rename array keys in PHP?
<p>When I var_dump on a variable called $tags (a multidimensional array) I get this:</p>

<pre>Array
(
    [0] => Array
        (
            [name] => tabbing
            [url] => tabbing
        )

    [1] => Array
        (
            [name] => tabby ridiman
            [url] => tabby-ridiman
        )

    [2] => Array
        (
            [name] => tables
            [url] => tables
        )

    [3] => Array
        (
            [name] => tabloids
            [url] => tabloids
        )

    [4] => Array
        (
            [name] => taco bell
            [url] => taco-bell
        )

    [5] => Array
        (
            [name] => tacos
            [url] => tacos
        )
)
</pre>

<p>I would like to rename all array keys called "url" to be called "value". What would be a good way to do this?</p>
