Try this:

preg_replace("/\s*[a-zA-Z\/\/:\.]*youtube.com\/watch\?v=([a-zA-Z0-9\-_]+)([a-zA-Z0-9\/\*\-\_\?\&\;\%\=\.]*)/i","<iframe width=\"420\" height=\"315\" src=\"//www.youtube.com/embed/$1\" frameborder=\"0\" allowfullscreen></iframe>",$post_details['description']);

A little enhancement of Joran's solution to handle also youtube short URL format:

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/$2\" allowfullscreen></iframe>",
        $string
    );
}

You can test this function online here

There are two types of youtube link :

For Example :

$type1 = 'https://www.youtube.com/watch?v=NVcpJZJ60Ao';
$type2 = 'https://www.youtu.be/NVcpJZJ60Ao';

These links refers to the same video. I found a function from here that handle the two links ! :

function getYoutubeEmbedUrl($url)
{
    $shortUrlRegex = '/youtu.be\/([a-zA-Z0-9_]+)\??/i';
    $longUrlRegex = '/youtube.com\/((?:embed)|(?:watch))((?:\?v\=)|(?:\/))(\w+)/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 $type1 or $type2 would be the same :

 $output1 = getYoutubeEmbedUrl($type1);
 $output2 = getYoutubeEmbedUrl($type2);

$output1 and $output2 :

'https://www.youtube.com/embed/NVcpJZJ60Ao'

Now you can use it in iframe!

A quick function for generating Embed url link of any of the FB/vimeo/youtube videos.

public function generateVideoEmbedUrl($url){
    //This is a general function for generating an embed link of an FB/Vimeo/Youtube Video.
    $finalUrl = '';
    if(strpos($url, 'facebook.com/') !== false) {
        //it is FB video
        $finalUrl.='https://www.facebook.com/plugins/video.php?href='.rawurlencode($url).'&show_text=1&width=200';
    }else if(strpos($url, 'vimeo.com/') !== false) {
        //it is Vimeo video
        $videoId = explode("vimeo.com/",$url)[1];
        if(strpos($videoId, '&') !== false){
            $videoId = explode("&",$videoId)[0];
        }
        $finalUrl.='https://player.vimeo.com/video/'.$videoId;
    }else if(strpos($url, 'youtube.com/') !== false) {
        //it is Youtube video
        $videoId = explode("v=",$url)[1];
        if(strpos($videoId, '&') !== false){
            $videoId = explode("&",$videoId)[0];
        }
        $finalUrl.='https://www.youtube.com/embed/'.$videoId;
    }else if(strpos($url, 'youtu.be/') !== false){
        //it is Youtube video
        $videoId = explode("youtu.be/",$url)[1];
        if(strpos($videoId, '&') !== false){
            $videoId = explode("&",$videoId)[0];
        }
        $finalUrl.='https://www.youtube.com/embed/'.$videoId;
    }else{
        //Enter valid video URL
    }
    return $finalUrl;
}

I know this is an old thread, but for anyone having this challenge and looking for assistance, I found a PHP Class on GitHub - Embera.

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!

回答6:

I think a safe, super simple way to get the id
which is kinda bulletproof is to simply use the URL structure.

function getYoutubeEmbedUrl($url){

    $urlParts   = explode('/', $url);
    $vidid      = explode( '&', str_replace('watch?v=', '', end($urlParts) ) );

    return 'https://www.youtube.com/embed/' . $vidid[0] ;
}

Below will work for all type of YouTube URLs.

preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $url, $match);

$youtube_id = $match[1];

回答8:

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:

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 ;)

With the video id you can embed the video ;)

回答9:

If the string is from user input, or in any way unpredictable, then forget using RegEx...seriously. It will open a can of worms for you.

Instead, try to look into using a HTML parser to extract the URL's based on certain rules and selectors.

I mainly use ColdFsuion / Java and JSoup is amazing for this kind of thing, with a whole lot more ease and security too.

It seems, in PHP, you could use something like this:

I'd love to give a code sample, but I don't know PHP well enough. But give it a go.

preg_match('/[\\?\\&]v=([^\\?\\&]+)/', $url, $matches);
