  1. function Get_links ($link) {
  2. $html = file_get_contents ($link);
  3. $html = Str_replace ("\ n", "", $html);
  4. $html = Preg_replace ('/$html = preg_replace ('/<\/a>/', "\ n", $html);
  5. Preg_match_all ('/.*?<\/a>/', $html, $matches);
  6. return ($matches);
  7. }
Copy Code
In this example, we want to use file_get_contents to get the content of a Web page. Then use Str_replace ("\ n", "", $html) to remove all the line breaks. Then use Preg_replace ('//', ' \ n ', $html) to put all the ... Mode to another line. Finally, the link mode is matched with Preg_match_all ('/.*?<\/a>/', $html, $matches). /.*?<\/a>/is a match ..... The regular expression of this pattern. Then why do we have to put ... Link to another line?? Because in the/.*?<\/a>/mode,. * is not able to match the line-wrapping, so as and not in the same line can not match!! So we're going to do this!
