本教程会将评论中留有网址、电话、QQ号码(5位以上数字)全部过滤掉，操作很简单，在模板文件中module.php中的<?php echo $comment['content']; ?>将其替换成如下代码即可：

<?php //过滤号码、网址

$qq = '/\0\d{2,3}-\d{5,9}|0\d{2,3}-\d{5,9}|0\d{2,3}\d{5,9}|0\d{2,3}\d{5,9}|[0-9]\d{2,3}\d{3,20}|[0-9]\d{1,10}-\d{1,20}|[0-9]\d{0,10}-\d{1,20}/';

$wz = '/(http:\/\/|https:\/\/|)[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\’:+!]*([^<>\"])*/';

$pbhm=preg_replace($qq,'【号码屏蔽】',$comment['content']);

echo preg_replace($wz,'【网址屏蔽】',$pbhm);

?>

如果要实现对管理员不过滤，请使用下面代码替换

<?php if(ROLE == ROLE_ADMIN){echo $comment['content'];}else{

$qq = '/\0\d{2,3}-\d{5,9}|0\d{2,3}-\d{5,9}|0\d{2,3}\d{5,9}|0\d{2,3}\d{5,9}|[0-9]\d{2,3}\d{3,20}|[0-9]\d{1,10}-\d{1,20}|[0-9]\d{0,10}-\d{1,20}/';

$wz = '/(http:\/\/|https:\/\/|)[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\’:+!]*([^<>\"])*/';

$pbhm=preg_replace($qq,'【号码屏蔽】',$comment['content']);

echo preg_replace($wz,'【网址屏蔽】',$pbhm);}

?>
