A little enhancement of Joran's solution to handle also youtube short URL format:
Joran 处理 youtube 短 URL 格式的解决方案的一些增强：
function convertYoutube($string) {
return preg_replace(
"/\s*[a-zA-Z\/\/:\.]*youtu(be.com\/watch\?v=|.be\/)([a-zA-Z0-9\-_]+)([a-zA-Z0-9\/\*\-\_\?\&\;\%\=\.]*)/i",
"<iframe src=\"//www.youtube.com/embed/\" allowfullscreen></iframe>",
$string
);
}

There are two types of youtube link for one video:
一个视频有两种类型的 YouTube 链接：
Example:
例子：
$link1 = 'https://www.youtube.com/watch?v=NVcpJZJ60Ao';
$link2 = 'https://www.youtu.be/NVcpJZJ60Ao';
This function handles both:
该函数同时处理：
function getYoutubeEmbedUrl($url)
{
$shortUrlRegex = '/youtu.be\/([a-zA-Z0-9_-]+)\??/i';
$longUrlRegex = '/youtube.com\/((?:embed)|(?:watch))((?:\?v\=)|(?:\/))([a-zA-Z0-9_-]+)/i';
if (preg_match($longUrlRegex, $url, $matches)) {
$youtube_id = $matches[count($matches) - 1];
}
if (preg_match($shortUrlRegex, $url, $matches)) {
$youtube_id = $matches[count($matches) - 1];
}
return 'https://www.youtube.com/embed/' . $youtube_id ;
}
The output of $link1 or $link2 would be the same :
$link1 或 $link2 的输出将是相同的：
$output1 = getYoutubeEmbedUrl($link1);
$output2 = getYoutubeEmbedUrl($link2);
// output for both: https://www.youtube.com/embed/NVcpJZJ60Ao
Now you can use the output in iframe!
现在您可以在 iframe 中使用输出了！

Basically an oembed library which converts YouTube URLs in any string into the associated iframe element. I'm using it, and will continue to use it everywhere!
基本上是一个 oembed 库，它将任何字符串中的 YouTube URL 转换为关联的 iframe 元素。我正在使用它，并将继续在任何地方使用它！

I think a safe, super simple way to get the id
which is kinda bulletproof is to simply use the URL structure.
我认为获取
有点防弹的 id 的一种安全、超级简单的方法是简单地使用 URL 结构。
function getYoutubeEmbedUrl($url){
$urlParts = explode('/', $url);
$vidid = explode( '&', str_replace('watch?v=', '', end($urlParts) ) );
return 'https://www.youtube.com/embed/' . $vidid[0] ;
}

Well, you need to filter out the youtube links first and put them into an array. Next you need to find out the video id of the url which is very easy. Use this script:
好吧，您需要先过滤掉youtube链接并将它们放入数组中。接下来，您需要找出网址的视频 ID，这很容易。使用这个脚本：
function getIDfromURL() {
var video_url = document.getElementById('url').value;
var video_id = video_url.split('v=')[1];
var ampersandPosition = video_id.indexOf('&');
if (ampersandPosition != -1) { video_id = video_id.substring(0, ampersandPosition); }
document.getElementById('url').value=video_id;
}
You can of course use a PHP function as well, but I just used JS here to get the id from the URL. Maybe that helped anyways ;)
你当然也可以使用 PHP 函数，但我这里只是使用 JS 从 URL 中获取 id。也许这有帮助；)
With the video id you can embed the video ;)
使用视频 ID，您可以嵌入视频 ;)

If the string is from user input, or in anyway unpredictable, then forget using RegEx...seriously. It will open a can of worms for you.
如果字符串来自用户输入，或者以任何方式不可预测，那么请忘记使用 RegEx...认真地。它会为你打开一罐蠕虫。
Instead, try to look into using a HTML parser to extract the URL's based on certain rules and selectors.
相反，尝试使用 HTML 解析器根据某些规则和选择器提取 URL。
