You have to ask users to store the 11 character code from the youtube video.
您必须要求用户存储 youtube 视频中的 11 个字符代码。
For e.g. http://www.youtube.com/watch?v=Ahg6qcgoay4
例如http://www.youtube.com/watch?v=Ahg6qcgoay4
The eleven character code is : Ahg6qcgoay4
十一字代码为：Ahg6qcgoay4
You then take this code and place it in your database. Then wherever you want to place the youtube video in your page, load the character from the database and put the following code:-
然后，您获取此代码并将其放入您的数据库中。然后，无论您想将 YouTube 视频放置在页面中的哪个位置，从数据库加载角色并输入以下代码：-
e.g. for Ahg6qcgoay4 it will be :
例如，对于 Ahg6qcgoay4，它将是：
<object width="425" height="350" data="http://www.youtube.com/v/Ahg6qcgoay4" type="application/x-shockwave-flash"><param name="src" value="http://www.youtube.com/v/Ahg6qcgoay4" /></object>

Do not store the embed code in your database -- YouTube may change the embed code and URL parameters from time to time. For example the <object>embed code has been retired in favor of <iframe>embed code. You should parse out the video id from the URL/embed code (using regular expressions, URL parsing functions or HTML parser) and store it. Then display it using whatever mechanism currently offered by YouTube API.
不要将嵌入代码存储在您的数据库中——YouTube 可能会不时更改嵌入代码和 URL 参数。例如，<object>嵌入代码已被淘汰，取而代之的是<iframe>嵌入代码。您应该从 URL/嵌入代码中解析出视频 ID（使用正则表达式、URL 解析函数或 HTML 解析器）并存储它。然后使用 YouTube API 当前提供的任何机制显示它。
A naive PHP example for extracting the video id is as follows:
一个用于提取视频 ID 的简单 PHP 示例如下：
<?php
preg_match(
'/[\?\&]v=([^\?\&]+)/',
'http://www.youtube.com/watch?v=OzHvVoUGTOM&feature=channel',
$matches
);
// $matches[1] should contain the youtube id
?>
I suggest that you look at these articles to figure out what to do with these ids:

From both long and short youtube urls you can get the embed this way:
从长和短的 youtube 网址，您都可以通过以下方式获得嵌入：
$ytarray=explode("/", $videolink);
$ytendstring=end($ytarray);
$ytendarray=explode("?v=", $ytendstring);
$ytendstring=end($ytendarray);
$ytendarray=explode("&", $ytendstring);
$ytcode=$ytendarray[0];
echo "<iframe width=\"420\" height=\"315\" src=\"http://www.youtube.com/embed/$ytcode\" frameborder=\"0\" allowfullscreen></iframe>";

The <object>and <embed>tags are deprecated as per HTML Youtube Videos, it is preferable to use the <iframe>tag to do so.
在<object>和<embed>标签不赞成每个HTML YouTube视频，最好使用<iframe>标签来做到这一点。
<iframe width="420" height="315"
src="http://www.youtube.com/embed/XGSy3_Czz8k?autoplay=1">
</iframe>
In order for your users not spend their entire lifetime trying to find the video id in links to put it in your form field, let them post the link of the video they find on youtube and you can use the following regex to obtain the video id:
为了让您的用户一生不会在链接中查找视频 ID 以将其放入表单字段，请让他们发布他们在 youtube 上找到的视频的链接，您可以使用以下正则表达式获取视频 ID ：
preg_match("/^(?:http(?:s)?:\/\/)?
(?:www\.)?(?:m\.)?(?:youtu\.be\/|youtube\.com\/(?:(?:watch)?\?(?:.*&)?v(?:i)?=|
(?:embed|v|vi|user)\/))([^\?&\"'>]+)/", $url, $matches);
To get the video id you can fetch it $matches[1], these will match:
要获取您可以获取的视频 ID $matches[1]，它们将匹配：
- youtube.com/v/vidid
- youtube.com/vi/vidid
- youtube.com/?v=vidid
- youtube.com/?vi=vidid
- youtube.com/watch?v=vidid
- youtube.com/watch?vi=vidid
- youtu.be/vidid
- youtube.com/embed/vidid

Use a regex to extract the "video id" after watch?v=
使用正则表达式提取“视频ID”之后 watch?v=
Store the video id in a variable, let's call this variable vid
将视频 id 存储在一个变量中，让我们调用这个变量 vid
Get the embed code from a random video, remove the video id from the embed code and replace it with the vidyou got.
从随机视频中获取嵌入代码，从嵌入代码中删除视频 ID 并将其替换为vid您获得的。
I don't know how to deal with regex in php, but it shouldn't be too hard
我不知道如何处理 php 中的正则表达式，但应该不会太难
Here's example code in python:
这是python中的示例代码：
>>> ytlink = 'http://www.youtube.com/watch?v=7-dXUEbBz70'
>>> import re
>>> vid = re.findall( r'v\=([\-\w]+)', ytlink )[0]
>>> vid
'7-dXUEbBz70'

Here is some code I've wrote to automatically turn URL's into links and automatically embed any video urls from youtube. I made it for a chat room I'm working on and it works pretty well. I'm sure it will work just fine for any other purpose as well like a blog for instance.
这是我编写的一些代码，用于自动将 URL 转换为链接并自动嵌入来自 youtube 的任何视频 URL。我为我正在工作的聊天室制作了它，并且效果很好。我相信它可以很好地用于任何其他目的，例如博客。
All you have to do is call the function "autolink()" and pass it the string to be parsed.
您所要做的就是调用函数“autolink()”并将要解析的字符串传递给它。
For example include the function below and then echo this code.
例如，包含下面的函数，然后回显此代码。
`
echo '<div id="chat_message">'.autolink($string).'</div>';
/****************Function to include****************/
<?php
function autolink($string){
// force http: on www.
$string = str_ireplace( "www.", "http://www.", $string );
// eliminate duplicates after force
$string = str_ireplace( "http://http://www.", "http://www.", $string );
$string = str_ireplace( "https://http://www.", "https://www.", $string );
// The Regular Expression filter
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
// Check if there is a url in the text
$m = preg_match_all($reg_exUrl, $string, $match);
if ($m) {
$links=$match[0];
for ($j=0;$j<$m;$j++) {
if(substr($links[$j], 0, 18) == 'http://www.youtube'){
$string=str_replace($links[$j],'<a href="'.$links[$j].'" rel="nofollow" target="_blank">'.$links[$j].'</a>',$string).'<br /><iframe title="YouTube video player" class="youtube-player" type="text/html" width="320" height="185" src="http://www.youtube.com/embed/'.substr($links[$j], -11).'" frameborder="0" allowFullScreen></iframe><br />';
}else{
$string=str_replace($links[$j],'<a href="'.$links[$j].'" rel="nofollow" target="_blank">'.$links[$j].'</a>',$string);
}
}
}
return ($string);
}
?>

You can do this simple with Joomla. Let me assume a sample YouTube URL - https://www.youtube.com/watch?v=ndmXkyohT1M
你可以用 Joomla 做到这一点。让我假设一个示例 YouTube URL - https://www.youtube.com/watch?v=ndmXkyohT1M

You can simply create a php input form for Varchar date,give it a varcharlength of lets say 300. Then ask the users to copy and paste the Embed code.When you view the records, you will view the streamed video.
您可以简单地创建一个 php 输入表单Varchar date，让它的varchar长度为 300。然后要求用户复制并粘贴嵌入代码。当您查看记录时，您将查看流式视频。
