Spam bots often 'scrape' pages to glean information and collect email addresses. I don't like that.
To combat the Bots from collecting my address off of my site, I wrote a script that includes 'obscures' the address in several ways.

It adds 'AT' where the '@' sign is and then replaces the '.' with 'DOT' so it is humanly readable, but not by the Bots.
Also, it encodes the 'mailto' and the address used in the 'mailto' so it shows okay on the web page and on:hover, but it is actually encode into hex values on the page. Sort of like Html Entities, which 'most' Bots cannot read. But they are becoming smarter all the time, so there is no guarantee that this will work all the time for all Bots..

The demo site can be used to create the obfuscated (Whew, big word!) link tag for use on your own site if you are new to Web site building and do not yet feel comfortable with coding php or templates..

Experienced Developers/Coders can download the core components from here. Three functions. I wrote the functions so the code would be re-usable for other tasks.

One function replaces the '@' and '.'.
The other one is a generic string encoding function. It could also be used to encode code snippets on your pages, too...

Nice bit of code there!

nowadays whenever i make a contact page i always use a PHP MAIL command to hide the address and i avoid writing my email address anywhere on the net too but it can be useful to create MAILTO links and this is a good way of protecting them

When making a website for a relative they needed a contact page and wanted an image link with a MAILTO so i may very well end up using this little snippet if thats ok with you?

Im more than happy to put a mention in the source code but as its for a paying client im reluctant to have a user-visible mark. Of course my use of the code is up to your discretion

I have a version which produces an Image link, too. The Image can get created dynamically, or from a saved file if it is available, but there is a problem with accessing the Fonts here on the Trap, so I didn't post that one.

If you need the code for the Image-based version, PM a request. It works fine on my localhost (XAMPP) installation. If you have GD with T1Lib installed, which a standard XAMPP does, it will likely work on your machine.

And all of my stuff is Licenced under the Creative Commons - attributtion - share-alike standards, so, yes, you may borrow the code. Simply retain the copyright in the script and pass it on. Whether you alter the code or not, the copyright needs to follow it.

A link-back is not required, but that would be nice.

Good news then! The copyright will follow it if i do indeed use this code. I wont put a link back thats visible because this website is for a paying client but if i use the code on any of my websites then i will definitely have a link back, i hope you dont mind that

I wont bother with the image code as im not a fan of using the GD library and image manipulation in PHP as its a bit too object orientated for me, but one day i will branch into OO PHP

Thanks for letting me and everyone else use the code, im sure it will be very useful

*UPDATED OCT 16/2007*

Fixes:
1.) Corrected the Download Link - removed an extra character in "iindex"
2.) Corrected the default email address displayed - removed a trailing 'a'
3.) Added additional check for bad User input - function to clean some bad stuff
4.) Converts html entities - again, a security issue

That should do it for now. Let me know if you have any difficulties with the script.

Thanks.

*UPDATED OCT 17/2007*

Fixes:

5.) Fixed validation of "&'s"in the Trap link
6.) Corrected Licence link to Creative Commons

I Encoded like this:

myname[dot]32[at]gmail[dot]com

But there is a another way, like:

Before: myname.32@gmail.com
After: NOSPAM---myname.32@gmail.com

Adding NOSPAM is great too.
