 /* -------- 输出 --------*/
Array ( [0] => 123

[2] => Array ( [0] => [b] <div class="box_con box_con_movieinfo">([\s\S]*?)<a target="_blank"[/b] ) )

------解决方案--------------------
PHP code

 $a ="[b] <div class=\"box_con box_con_movieinfo\">([\s\S]*?)<a target=\"_blank\"[/b]";
 $b = htmlspecialchars($a);
 $c = array(123,$b,array($b));

$d = htmlspecialchars_decode($c[2][0]);
echo "d-->>".$d."<br>";
/*输出，浏览器界面已将标签解析*/
d-->>[b] 
([\s\S]*?)
/*源码*/
d-->>[b] <div class="box_con box_con_movieinfo">([\s\S]*?)<a target="_blank"[/b]<br>
