php regex to get string inside href tag

I have a text file where there are multiple occurrences of href tag.

I wish to get the content of these

href='...'

and print it to screen.

How can I achieve that? The main problem is writing a correct regex.

Here you go:

$pageData = file_get_contents('your.txt');
if(preg_match_all('/<a\s+href=["\']([^"\']+)["\']/i', $pageData, $links, PREG_PATTERN_ORDER))
    $all_hrefs = array_unique($links[1]);

Now you have all unique hrefs in $all_href;

if you want to display them:

foreach($all_href as $href)
{
echo $href;
}
