小编New*_* Co的帖子

我正在使用Bootstrap.

我有一个包含2或3个基于iframe的嵌入视频的文字.

此数据从数据库中获取.

如何让这些iframe响应？

示例代码:

<div class="row">

   <div class="col-lg-12 col-md-12 col-sm-12">

     SOME TEXT SOME TEXT SOME TEXT SOME TEXT
     SOME TEXT SOME TEXT SOME TEXT SOME TEXT

     <iframe src="http://youtube.com/...."></iframe>

     SOME TEXT SOME TEXT SOME TEXT SOME TEXT
     SOME TEXT SOME TEXT SOME TEXT SOME TEXT

     <iframe src="http://youtube.com/...."></iframe>


     SOME TEXT SOME TEXT SOME TEXT SOME TEXT
     SOME TEXT SOME TEXT SOME TEXT SOME TEXT

     <iframe src="http://youtube.com/...."></iframe> 

   </div>

</div>

这是一个动态数据.我怎样才能使其响应？

我想只从php字符串中提取文本.

这个php字符串包含html代码,如标签等.

所以我只需要这个字符串中的简单文本.

这是实际的字符串:

<div class="devblog-index-content battlelog-wordpress">
<p><strong>The celebration of the Recon class in our second </strong><a href="http://blogs.battlefield.com/2014/10/bf4-class-week-recon/" target="_blank">BF4 Class Week</a><strong> continues with a sneaky stroll down memory lane.

<p>&nbsp;</p>

<p style="text-align:center"><a href="http://eaassets-a.akamaihd.net/battlelog/prod/954660ddbe53df808c23a0ba948e7971/en_US/blog/wp-content/uploads/2014/10/bf4-history-of-recon-1.jpg?v=1412871863.37"><img alt="bf4-history-of-recon-1" class="aligncenter" src="http://eaassets-a.akamaihd.net/battlelog/prod/954660ddbe53df808c23a0ba948e7971/en_US/blog/wp-content/uploads/2014/10/bf4-history-of-recon-1.jpg?v=1412871863.37" style="width:619px" /></a></p>

我想从字符串中显示:

The celebration of the Recon class in our second BF4 Class Week continues with a sneaky stroll down memory lane. Learn more about how the …

我试图在Lumen框架中运行以下查询:

SELECT * FROM user WHERE (username = $username OR email = $username) AND password = $password AND flag = 1;

我的流明代码:

$login =  User::where('pass', '=', md5($pass))
               ->where('flag', '=', $flag)
               ->where('username', '=', $username)
               ->orWhere('email', '=', $username)->first();

不知何故,此代码始终返回true并绕过登录.那个查询有什么问题？

当我orWhere从查询中删除它适用于用户名.
