Finding Data In Meta Tags using php to search Meta Tags for data

In the Head portion of an Html file, there are usually several Meta Tags that contain data about various things, like the tag for keywords, an Author's name or maybe a description field.

Here are two example Meta tags:

<meta name="Keywords" content="keyword1, keyword2" />
 <meta name="Description" content=" A Description of the file's content is here" />

So, what I have a question about concerns checking a file to see what information is included in these tags and using that information as variables or content in the output of the page. For example, if I wanted to find the information included in the content="..." field in either of these two meta tags, what php variable would I check or how would I find it from inside the php page?

Then I wish to output it using an echo or print command. Is this possible?

Okay.... Never mind, I found the answer.

How about I just use "get_meta_tags ()" and the array elements found in that?
