array keys to lowercase

[Anon]

hi,

I'm using the following to get the Meta tags off a page:

$metatags = get_meta_tags ("mypage.html");
echo "$metatags[keywords]";

But what if someone codes their pages using "KEYWORDS" or "Keywords" in their meta tags? is there any way to make the array keys lowercase? For the actual values of the keys, I guess you could just loop through each element and use strtolower(), but I don't know how to get the keys into lowercase. Anyone help? Cheers.

According to the documentation:
http://www.php.net/manual/en/function.get-meta-tags.php
all the keys are lower case already.
