Get a YouTube video URL in PHP

Quick piece of code that should, in theory, fetch the FLV/MP4/whatever URL of the video, given a youtube URL.


The example has a hard-coded url, turn it into a function to make it a parameter instead.


Also, it has absolutely no error checking, so you may wanna implement that (e.g. you should check if $r returns false and, if so, throw an error and die).

$c = curl_init();curl_setopt($c, CURLOPT_URL, 'http://www.youtube.com/watch?v=sRLz4aDCAs0');curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);curl_setopt($c, CURLOPT_FAILONERROR, 1);$r = curl_exec($c);curl_close($c);
preg_match_all('#url_encoded_fmt_stream_map=([^&]+)#', $r, $fvars);$fvars = explode('&', urldecode($fvars[1][0]));
$results = array();$resultIndex = -1;
foreach($fvars as $item){    if(strpos($item, 'url=') !== false)        $resultIndex++;    if(!isset($results[$resultIndex]))        $results[$resultIndex] = array();    if(strpos($item, 'url=') === false)    {        $parse = explode('=', $item);        $results[$resultIndex][$parse[0]] = urldecode($parse[1]);        continue;    }    $parse = preg_match('#url=(.+)$#', $item, $url);    $results[$resultIndex]['url'] = urldecode($url[1]);}
var_dump($results);

PHP:

This results in an array containing arrays like so:

  array(5) {
    ["url"]=>
    string(419) "some_youtube_url"
    ["quality"]=>
    string(5) "small"
    ["fallback_host"]=>
    string(26) "tc.v4.cache5.c.youtube.com"
    ["type"]=>
    string(11) "video/x-flv"
    ["itag"]=>
    string(1) "5"
  }

Code (markup):

Just an example anyway, there may be an easier way to do it but this seemed logical at the time.

 

I am looking for this, thanks for sharing.

 

thanks brother....good job....

 

but if a link youtube get file hd that it is file wmv, how can you get it

 

Thank WPC post code example, i'll post code check file HD if it exist or not exist get file flv

function getYouTube($url)
{    
$geturl = NULL;    
$c = curl_init();    
curl_setopt($c, CURLOPT_URL,$url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_FAILONERROR, 1); 
$err = curl_error($c);
$r = curl_exec($c);
curl_close($c);
if(isset($err))
{
$geturl = "Link Warn Video Not Found";    
}else{   
 preg_match_all('#url_encoded_fmt_stream_map=([^&]+)#', $r, $fvars);    
$fvars = explode('&', urldecode($fvars[1][0]));        
$results = array();    
$resultIndex = -1;   
foreach($fvars as $item)    
{       
 if(strpos($item, 'url=') !== false)$resultIndex++;               
 if(!isset($results[$resultIndex]))$results[$resultIndex] = array();       
 if(strpos($item, 'url=') === false)        
{            
$parse = explode('=', $item);            
$results[$resultIndex][$parse[0]] = urldecode($parse[1]);            
continue;        
}                
$parse = preg_match('#url=(.+)$#', $item, $url);        
$results[$resultIndex]['url'] = urldecode($url[1]);    
}
//video/mp4; codecs="avc1.42001E, mp4a.40.2"    
$searchType = "/mp4/i";    
foreach($results as $test)    
{        
if(preg_match($searchType,$test["type"]))        
{            
$geturl = $test["url"];            
echo "Type {$test["type"]} and link file {$test["url"]}";            
break;        
}    
}    
if(empty($geturl))    
{        
$geturl = $results[0]["url"];    
}    
}    
return $geturl;
}

PHP:

Call Function

echo getYouTube("http://www.youtube.com/watch?v=sRLz4aDCAs0");

PHP:

 

This code can get clip embed author right?

 

This is code get url file movies let you can set embed with Flash Player like JW Payer, MP Player ...etc

 

If you want to embed with JW, I think you no need so much to do like that.

I have done with this code:

That's enough to show youtube clip on my page.

 

it need for working if you're want to track visits or to download that file and hide the address link movies of the file
