如何检查到一篇文章中有连结就自动加上标签?

时间：2021-07-01 10:21:17 帮助过：19人阅读

以为不能用网上的既有的资源，以及比较难搞的点...就是内容是还有可能需要过滤图片及影片的网址(iframe)

我用了以下这一段做自动检测有连结的话就自动加上

但问题是有时候是图片

有时间是影片.(影片将会以iframe)模式显示

所以想请教一下，如何才能把图片() 影片() 这类东西过滤(跳过不处理)</strong> <br /> <br /> 获得的$content已经是已成HTML的代码 <br /> <br /> <pre class="sycode" name="code"> $content= preg_replace_callback('#(?:https?://\S+)|(?:www.\S+)|(?:\S+\.\S+)#', function($arr) { if(strpos($arr[0], 'http://') !== 0) { $arr[0] = 'http://' . $arr[0]; } $url = parse_url($arr[0]); //links return sprintf('%1$s', $arr[0]); }, $content);</pre> <p> </p> </p> <br /> <h2>回复讨论(解决方案)</h2> <p class="sougouAnswer"> ?考： http://blog.baiwand.com/?post=150 </p> <p class="sougouAnswer"> <p class="yy"> 参考：
