Printing array values | Meta Tag Analyzer
I have an array that I would like to print out.
I have a test form up here that will analyze a given site's meta tags. I would like to simply get the meta-tags, and then list them or put them into a table...
So far, here is what I have:
http://metataggenerator.org/analyzer/
You can enter an URL into the box and the script will print out the meta tags in a list or table.
The code thus far:

$url = "http://$url"; // adds http:// to the URL in case the user forgets it...
