I was using javascript to obfuscate my email addresses from spambots but it didn’t validate as strict XHTML under W3C so I was searching for a PHP solution. Here is a super easy solution which validates as XHTML Strict.

< ?php
// store the email address in a string variable
$email= "webmaster@example.com";
// get the length of the email address
$length = strlen($email);
// work your way through each 
//character of the email address
for ($i = 0; $i < $length; $i++)
// get the deicmal ASCII value of the character
$obfuscatedEmail .= "&#" . ord($email[$i]) . ";";
?>

I have to give where credit is due so thanks to Aaron Toponce for this Obfuscate email PHP style.

Note: I did change the last line since I was receiving an error “reference not terminated by REFC delimiter” even though Aaron original code was validating as Strict XHTML. The code is dated back Nov 2005 but still functions. =)

Harvest for Christ
