超链接 Youtube 以嵌入代码

发布于 2024-10-12 02:56:26 字数 2123 浏览 4 评论 0原文

我在使用 Preg_replace 和 preg_match_all 将 Youtube URL 转换为嵌入代码时遇到一些麻烦。是的，我知道这个话题已经在 stackoverflow 中涉及到了，但并不完全像我想要的那样。

我可以从一个没有 html 的 url 中获取 ID：

http://(?:www\.)?youtu(?:be\.com/watch\?v=|\.be/)(\w*)(&(amp;)?[\w\?=]*)?

但我的 url 格式如下：

<a href="http://www.youtube.com/watch?v=C9KAqhbIZ7o" class="comment-link">http://www.youtube.com/watch?v=C9KAqhbIZ7o</a>

我想将其全部转换为：

<object width="640" height="505"><param name="movie" value="http://www.youtube.com/v/C9KAqhbIZ7o?fs=1&amp;hl=es_ES&amp;rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/C9KAqhbIZ7o?fs=1&amp;hl=es_ES&amp;rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="505"></embed></object>

有人可以施展一些魔法，告诉我检测所有内容的正确表达式url，获取一次 ID 并将其全部转换为嵌入代码？提前非常感谢！

我想得到这个：

谢谢大家的帮助，我真的很感激！

I've some troubles using Preg_replace and preg_match_all to convert a Youtube URL to embed code. Yes, I know that this topic has already touched in stackoverflow but not exactly like I want.

I can get the ID from a url, without html, with that:

http://(?:www\.)?youtu(?:be\.com/watch\?v=|\.be/)(\w*)(&(amp;)?[\w\?=]*)?

But I've the url formatted with like this:

<a href="http://www.youtube.com/watch?v=C9KAqhbIZ7o" class="comment-link">http://www.youtube.com/watch?v=C9KAqhbIZ7o</a>

And I want to convert it all to this:

<object width="640" height="505"><param name="movie" value="http://www.youtube.com/v/C9KAqhbIZ7o?fs=1&hl=es_ES&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/C9KAqhbIZ7o?fs=1&hl=es_ES&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="505"></embed></object>

Somebody can do some magic and tell me the correct expression to detect all the url, get the ID once and convert all to an embed code? Thank you so much in advance!

Thanks all for your help, I really appreciate it!

我用这个代码

        // url of video
    $url = $row['url'];
    $id=0;
    // we get the unique video id from the url by matching the pattern
    preg_match("/v=([^&]+)/i", $url, $matches);
    if(isset($matches[1])) $id = $matches[1];
    if(!$id) {
        $matches = explode('/', $url);
        $id = $matches[count($matches)-1];
    }
    // this is your template for generating embed codes
    $code = '<div id="img_wrapper"><object width="640" height="458"><param name="movie" value="http://www.youtube.com/v/{id}&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/{id}&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object></div>';

    // we replace each {id} with the actual ID of the video to get embed code for this particular video
    $code = str_replace('{id}', $id, $code);

    echo $code;

I use this code

将 $html 替换为需要解析的 html 字符串。

$html=<<<HTML

HTML;


$regex="/v\=([\-\w]+)/";

preg_match_all($regex,$html,$out);

$out[1]=array_unique($out[1]);

foreach($out[1] as $o){

        $reg="/(<a).*(youtube.com).*($o).*(\/a>)/";

        $embed= <<<HTML
        <object width="640" height="505"><param name="movie" value="http://www.youtube.com/v/$o=1&hl=es_ES&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/$o?fs=1&hl=es_ES&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="505"></embed></object>
HTML;

        $html=preg_replace($reg,$embed, $html);

}

echo $html;

Replace $html with your html string which needs parsing.

$html=<<<HTML
