: www.l.google.com. 272 IN A 74.125.153.105
: www.l.google.com. 272 IN A 74.125.153.106
: www.l.google.com. 272 IN A 74.125.153.147
: www.l.google.com. 272 IN A 74.125.153.99
: www.l.google.com. 272 IN A 74.125.153.103
: 用php作开发，想请问一下
: 上面字串中若只想撷取ip及数字部份该如何表示
: 想了蛮久的 但还是不知道该如何作 麻烦各位为我解惑了
$str = '
www.l.google.com. 272 IN A 74.125.153.104
www.l.google.com. 272 IN A 74.125.153.105
www.l.google.com. 272 IN A 74.125.153.106
www.l.google.com. 272 IN A 74.125.153.147
www.l.google.com. 272 IN A 74.125.153.99
www.l.google.com. 272 IN A 74.125.153.103
';
preg_match_all('/\s+([\d]+)[^\d]+([\d\.]+)/sim', $str, $match);
echo '<pre>';
print_r($match);
echo '</pre>';
===============> 结果 <===============
Array
(
[0] => Array
(
[0] => 272 IN A 74.125.153.104
[1] => 272 IN A 74.125.153.105
