- preg_match_all("'<\s*a\s.*?href\s*=\s*(["\'])?(?(1)(.*?)\\1|([^\s\>]+))[^>]*>?(.*?)</a>'isx",$document,$links);
- while(list($key,$val) = each($links[2])) {
- if(!empty($val))
- $match['link'][] = $val;
- }
- while(list($key,$val) = each($links[3])) {
- if(!empty($val))
- $match['link'][] = $val;
- }
- while(list($key,$val) = each($links[4])) {
- if(!empty($val))
- $match['content'][] = $val;
- }
- while(list($key,$val) = each($links[0])) {
- if(!empty($val))
