How do I fetch the meta tags from a webpage using PHP?

Believe it or not, there is actually a built in PHP function to do this for you so you don't have to write your own parser or get down to looking at certain regular expressions in order to extract the relevant information from the page.

So here is how this function works practically.

Let's say we wanted to get the information for the PHP Questions homepage, then all we do is the following:


<?php

$gettags = get_meta_tags('http://www.php-questions.com/');



foreach($gettags as $i => $v) echo "$i - $v \n\n";



//outputs: description - PHP Questions contains a range of common questions and answers related to various aspects of PHP...



//keywords - php,questions,answers,php faq



?>

Note that, if available, this will also return the 'author' and 'geo_position' information for a webpage.
