You can Get Mp3 Tags without fully downloading the File.WE download file in chunks ,WE extract first and last 64 kb of the file Using ID3 PHP library and CURL.
I have created a function that will do that
Download id3 library and include it in your script .
PHP Code:
require_once("id3/getid3.php");
function 
getfileinfo($remoteFile)
*
{
*
$url=$remoteFile;
$uuid=uniqid("designaeon_"true);
*
$file="temp/".$uuid.".mp3";
*
$size=0;
*
$ch curl_init($remoteFile);
*
//==============================Get Size==========================//
*$contentLength 'unknown';
*
$ch1 curl_init($remoteFile);
*
curl_setopt($ch1CURLOPT_NOBODYtrue);
*
curl_setopt($ch1CURLOPT_RETURNTRANSFERtrue);
*
curl_setopt($ch1CURLOPT_HEADERtrue);
*
curl_setopt($ch1CURLOPT_FOLLOWLOCATIONtrue); //not necessary unless the file redirects (like the PHP example we're using here)
*$data curl_exec($ch1);
*
curl_close($ch1);
*if (
preg_match('/Content-Length: (\d+)/'$data$matches)) {
*
$contentLength = (int)$matches[1];
*
$size=$contentLength;
*}
*
//==============================Get Size==========================//
*
*if (!
$fp fopen($file"wb")) {
*echo 
'Error opening temp file for binary writing';
*return 
false;
*} else if (!
$urlp fopen($url"r")) {
*echo 
'Error opening URL for reading';
*return 
false;
*}
*try {
*
$to_get 65536// 64 KB
*$chunk_size 4096// Haven't bothered to tune this, maybe other values would work better??
*$got 0$data null;
*
*
// Grab the first 64 KB of the file
*while(!feof($urlp) && $got $to_get) {
*
$data $data fgets($urlp$chunk_size);
*
$got += $chunk_size;
*}
*
fwrite($fp$data);
*
*
// Grab the last 64 KB of the file, if we know how big it is.
*if ($size 0) {
*
curl_setopt($chCURLOPT_FILE$fp);
*
curl_setopt($chCURLOPT_HEADER0);
*
curl_setopt($chCURLOPT_RESUME_FROM$size $to_get);
*
curl_exec($ch);
*}
*
*
// Now $fp should be the first and last 64KB of the file!!
*
@
fclose($fp);
*@
fclose($urlp);
*} catch (
Exception $e) {
*@
fclose($fp);
*@
fclose($urlp);
*echo 
'Error transfering file using fopen and cURL !!';
*return 
false;
*}
*
$getID3 = new getID3;
*
$filename=$file;
*
$ThisFileInfo $getID3->analyze($filename);
*
getid3_lib::CopyTagsToComments($ThisFileInfo);
*
unlink($file);
*return 
$ThisFileInfo;
