preg_match_all doesn't match when using a carat (^)

Question

I\'m using preg_match_all to find a URL in a HTML file. The URL always appears at the start of the line, with no leading space, like this:

Answer 1

^ matches start-of-string not start-of-line. Use the m ("multi-line") modifier: //m

Answer 2

You have to add the m modifier:

preg_match_all('|^<A HREF="(?<url>.*?)"><strong>Next</strong>|m', $html, $url_matches);

then ^ matches at start of a line, else it would only match at the start of the entire string.
