Hi! I am trying to write an Anti Leeching script in PHP and have the following code: [code]<?php $referer=$_SERVER['HTTP_REFERER']; //Finds the referer and stores it into $referer //Edit from here //The following array contains the URL's from where the download can be accessed. //Usually you should put the name of your site here along with any subdomains from where //you want to allow files to be downloaded //The format is: //$sites[0]="http://example.com"; //$sites[1]="http://subdomain.example.com"; //$sites[2]="http://friendssite.com"; //and so on and so forth... $sites[0]="http://example.com"; $sites[1]="http://www.example.com"; $sites[2]="http://subdomain.example.com"; $sites[3]="http://www.subdomain.example.com"; $sites[4]="http://localhost"; $last=4; //Change 4 to the last number in your array, i.e, the number in [] of $sites. // In the default file it is $sites[4]="http://localhost"; and our number is 4 $length=16; //Enter the length of the shortest URL. In the default file it is http://localhost and the //length of it is 16, so I have entered 16. Please remember to count the whole thing including //http:// and www. or ftp:// $folder="downloads/".$go; //Enter the name of the secret folder where you store your downloads $anti_leech_page="anti_leech.php"; //Enter the file name of the page which you want to show if somebody //is caught leeching $wrong_access="access.php"; //Enter the file name of the page which you want to show if the anti leeching //script is accessed directly //Please don't edit beyond this point unless you know what you are doing //Truncating the referer $res=substr($referer,0,$length); echo($res); //Truncating the string of the URL's for ($i=0; $i<=$last; $i++) { $site[$i]=substr($sites[$i],0,$length); } /* for ($k=0; $k<=$last; $k++) { echo($site[$k]); echo("<br />"); } */ //Checking whether HTTP_REFERER is NULL if ($go=="") { $dummy=$wrong_access; } //If HTTP_REFERER is not NULL this happens for ($p=0; $p<=$last; $p++) { if ($site[$p]==$res) { $k=1; break; } else { $dummy=$anti_leech_page; } } if ($k=1) { $wer=$folder; } else { $wer=$dummy; } echo($folder); echo("<br />"); echo($wer); echo("<br />"); echo($dummy); echo("<br />"); ?> <!-- This is the HTML code of Abhishek's Anti Leeching Script --> <html> <head> <title>Abhishek's Anti Leeching Script</title> <!-- <meta http-equiv="refresh" content="1;url=<?php echo($wer); ?>"> --> </head> <body> Your download will begin in 1 seconds.

If it dosen't start, please click here. Referer is: [a href=\"http://localhost/abhishek/leech/main.php\" target=\"_blank\"]http://localhost/abhishek/leech/main.php[/a][/quote] First of all, the value of $go is not recognised. Second, though [a href=\"http://localhost\" target=\"_blank\"]http://localhost[/a] exists in the array, still $dummy is given the value of $anti_leech_page. Can you please help me out with this code. Thank you. Abhishek.
