I’ve used a simple file_get_contents function but that didn’t get the actual contents (output) of that..

I could not figure the error!!!

Code:

<?php 

// $url = $_GET['url'];

// $flv_http_path = urlencode($url);

 $flv_http_path = 'http://r12.bhartibb-maa1.c.youtube.com/videoplayback?ip=0.0.0.0&sparams=id%2Cexpire%2Cip%2Cipbits%2Citag%2Calgorithm%2Cburst%2Cfactor%2Coc%3AU0dXSlBSUl9FSkNNN19ITFZB&algorithm=throttle-factor&itag=34&ipbits=0&burst=40&sver=3&expire=1285074000&key=yt1&signature=3E1E4994130745C392FA479F6ACCE5F40E703A2C.A87325A1DCB178B04FD89A9DEEE811CDCB08157C&factor=1.25&id=8b2fd4fd9ac2f09f&st=lc';

 echo "----$flv_http_path------";


 $data = file_get_contents($flv_http_path);

 echo "$data";

 if($data)
    echo "data is avail";
 else
    echo "data not available";

// $new_flv_path = dirname(_FILE_).'/flvs/sample.flv' ;

 $new_flv_path = '/home/public_html/temp/sample.flv' ;

 if(file_put_contents($new_flv_path, $data))
    return $new_flv_path ;
 else
 {
    echo "else part ";
    return false;
 }

?>

I got that url from the response headers of the youtube video

    It’s youtubes way of preventing you from grabbing their flv files automatically.

    You can’t get the file from your server because the download link (which you got from your browser, or how did you find the flv link) is locked to your browser.

    Which is why when someone other than you try to call the link we all get the 403 HTTP forbidden, even with a spoofed user-agent.

    Try to use cURL and show the headers, you’ll see what I mean.
