如何用嵌入代码(在PHP中)替换文本中的Youtube网址?

问题描述

这是我到目前为止所得到的:

This is what I've got so far:

<?php

 $content = "word1 http://www.youtube.com/watch?v=yqfKe-67foQ&feature=related word2 http://www.youtube.com/watch?v=2vq7gDEn99Y&feature=related word3 http://www.youtube.com/watch?v=nW5HxgMYRto\nhttp://www.youtube.com/watch?v=8Uc2lpH0iZ0&feature=fvhl";
 $pattern = '/http:\/\/www\.youtube\.com\/watch\?(.*)v=([a-zA-Z0-9_\-]+)(\S*)/i';
 $replace = '<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/$2&amp;hl=en_US&amp;fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/$2&amp;hl=en_US&amp;fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>';

 $content = preg_replace($pattern, $replace, $content);
 echo $content;

?>

老实说，我不知道为什么它不起作用.一些帮助，将不胜感激.谢谢.

I honestly have no idea why it doesn't work. Some help would be appreciated. Thanks.

推荐答案

您只需要使 * 不贪心:

http:\/\/www\.youtube\.com\/watch\?(.*?)v=([a-zA-Z0-9_\-]+)(\S*)
