如何用正則解析這樣的字串？

形如：

$str='
hhhhhhhhhhhhh
'$str='
jjjjjjjjjjjjjjjj
'

想要得到p或者h1之間的內容,怎麼寫？

回複內容：

形如：

$str='
hhhhhhhhhhhhh
'$str='
jjjjjjjjjjjjjjjj
'

想要得到p或者h1之間的內容,怎麼寫？

([\s\S]+?)<\/\1>/';$str='
hhhhhhhhhhhhh
';preg_match($reg, $str, $result);var_dump($result);$str='
jjjjjjjjjjjjjjjj
';preg_match($reg, $str, $result);var_dump($result);

運行結果:

array(3) {  [0]=>  string(20) "
hhhhhhhhhhhhh
"  [1]=>  string(1) "p"  [2]=>  string(13) "hhhhhhhhhhhhh"}array(3) {  [0]=>  string(25) "
jjjjjjjjjjjjjjjj
"  [1]=>  string(2) "h1"  [2]=>  string(16) "jjjjjjjjjjjjjjjj"}

$reg='#<([\w]+)>(.+?)<\/\1>#s'
