[PHP] Download Manager Support

In need of a php programmer to fix up a download script too support Pause and Resume from download Managers such as FlashGET.

Currently if someone pauses then resumes a download they end up with a different amount of bytes causing the file to be corrupted.

pm me with how much $ you would like to solve this problem.

Example of the download code

<?
$time = time();
$mysql = mysql_connect("zzzzz:3306","zzzz","]zzzz");
mysql_select_db("zzz_zzzz", $mysql);
include("../mine-types.php");
$pass = mysql_fetch_array(mysql_query("SELECT MD5(CONCAT(MD5('{$_SERVER['PHP_AUTH_PW']}'), salt)) as enteredpass, password FROM user WHERE  username = '{$_GET['user']}'"),MYSQL_ASSOC);


if (!isset($_SERVER['PHP_AUTH_USER']) ||
     ($pass['enteredpass'] !=$pass['password'])) {
     
    authenticate();
    
}

	$t = mysql_fetch_array(mysql_query("SELECT * FROM `adl_tickets` WHERE `code` = '{$_GET['code']}' LIMIT 1"),MYSQL_ASSOC);

	if ($t['time'] >= $time-(60*60*24*7*2)){	
	
		$db = mysql_fetch_array(mysql_query("SELECT * FROM adl_files WHERE id= '{$_GET['id']}'  LIMIT 1"),MYSQL_ASSOC);
								
		$updatedls = mysql_query("INSERT INTO adl_downloads (filename, filesize, username, timestamp) VALUES ('{$db['filename']}','{$db['filesize']}','{$_GET['user']}','{$time}')");
		$insertdownloads = mysql_query("update adl_files set download_count = ( download_count + 1 ) WHERE id = '{$_GET['id']}' LIMIT 1");
		
		$size = $db['filesize'];
		$mtype=$type[$db['extension']];
		header('Expires: 0');
		header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
		header("Content-Type: $mtype");
		header("Accept-Ranges: bytes");
		header( "Content-Disposition: filename='".$db['filename']."';" );
		header( 'Content-Disposition: attachment; filename="'.$db['filename'].'"');
		header("Content-transfer-encoding: binary");
						
		if(isset($_SERVER['HTTP_RANGE'])){		
		
			list($a, $range) = explode("=",$_SERVER['HTTP_RANGE']);
			str_replace($range, "-", $range);
			$size2 = $size-1;
			$new_length = $size-$range;
			header("HTTP/1.1 206 Partial Content");
			header("Content-Length: $new_length");
			header("Content-Range: bytes $range$size2/$size");
		
		}else{
		
			header("Content-Length: ".$size);
			
		}
		    
		readfile("zzzzz/".$db['series']."/".$db['filename']);
    
	}else{
	
		$deleteticket = mysql_query("DELECT FROM adl_tickets WHERE code= '{$_GET['code']}'  LIMIT 1");
		echo "Sorry, your ticket has expired go back and try to download again. 
	}
	
	
	function authenticate() {
    header('WWW-Authenticate: Basic realm="zzzz"');
    header('HTTP/1.0 401 Unauthorized');
    echo "You must enter a valid login ID and password to access this resource\n";
    exit;
}
 

?>
