Answer 1

If you want to match the whole thing from :

$r = '`\]+)href\=\"mailto\:([^">]+)\"([^>]*)\>(.*?)\<\/a\>`ism';
preg_match_all($r,$html, $matches, PREG_SET_ORDER);

To fastern and shortern it:

$r = '`\]+)href\=\"mailto\:([^">]+)\"([^>]*)\>`ism';
preg_match_all($r,$html, $matches, PREG_SET_ORDER);

The 2nd matching group will be whatever email it is.

Example:

$html ='
test
';

$r = '`\]+)href\=\"mailto\:([^">]+)\"([^>]*)\>(.*?)\<\/a\>`ism';
preg_match_all($r,$html, $matches, PREG_SET_ORDER);
var_dump($matches);

Output:

array(1) {
  [0]=>
  array(5) {
    [0]=>
    string(39) "test"
    [1]=>
    string(1) " "
    [2]=>
    string(13) "test@live.com"
    [3]=>
    string(0) ""
    [4]=>
    string(4) "test"
  }
}
