mailto: Email Link Obfuscation (Hiding)

by

After searching for a good email link obfuscation script that allows the address to be seen as normal text i came upon a webpage that had a good solution, so i did a little reverse engineering and created this PHP script to output the same code, enjoy!

$v){
            $domain_array[$k] = strToHex($v,'%');
        }
        $domain = "'".implode("','",$domain_array);
        $domain .= "'";
        $output = $var1."=['".$user."',[".$domain."].reverse().join('.')].join('@');".$var2."=unescape(".$var1.");document.write(".$var2.".link('mai'+'lto:'+".$var1."));";
        $output = "";
        echo $output;
    }else{
        return false; //email address is not valid
    }
}

mailto_link('username@domain.com'); //use this function wherever you want an email link
?>

Simple Standalone PHP Web Counter

by

In my search for a simple PHP web counter it was difficult to find one that wasn’t somehow connected to an external host and didn’t write IP addresses to a file and then use resources to search the file later.  With all the NAT firewalls out there counting visitors based on IP address just doesn’t seem like a modern thing to do. I took a script by Eric Sizemore and modified it to create my own version.  What it does is add to the visitor count (stored in a txt file on the server) if they don’t have a cookie showing that they have visited before, then i set that cookie to expire after 60 days, after that if the visitor comes again they will be counted again.  It’s not the most accurate, but gives a good idea of how many people are visiting and i wanted to reduce server file operations.

The Code

  Simple Standalone PHP Web Counter (9.6 KiB, 904 hits)

Installation & Usage

  1. Unzip the code into your website’s root folder
  2. Change permissions on the counter log txt file so that it is writable (chmod 666).
  3. Add the following PHP code at the top of each root page you would like to display the counter on:
  4. Add the following PHP code where you want to have the counter display:
  5. Test the page you’ve included counter.php on and have show_counter() displayed.
