A question that gets asked all the time on forums is “How do I get all links on a web page” inside of <a> tags, so here’s some code with full commenting for each line

/**
 * @author Jay Gilford
 */

// regular expression pattern to match all links on a page
$pattern = '%]+href="(?P[^"]+)"[^>*]*>(?P[^< ]+)%si';

// Webpage URL to get links from
$url = 'http://www.jaygilford.com/';

// Fetch contents of whole page
$page_content = file_get_contents($url);

// Get all matches of links and put them into the $matches variable
preg_match_all($pattern, $page_content, $matches);

// Variable to hold all of our urls and their text
$urls = array();

// Loop through each array item
foreach($matches['url'] as $k=>$v) {
    // combine the url and text into it's own key for ease of access
    $urls[$k] = array('url' => $v,'text' => $matches['text'][$k]);
}

// For display purposes only to show the contents of $urls
echo print_r($urls, true);
