Here's a bit of PHP code that emits javascript. The javascript emits an email link, but coded in Javascript, so that most spiders won't be able to get your email address for spamming.
<?php
function printEmailAddress( $email )
{
$parts = explode( '@', $email );
echo ' var d = document;';
echo 'd.write("");';
echo 'd.write("'.$parts[0].'");';
echo 'd.write("@");';
echo 'd.write("'.$parts[1].'");';
echo 'd.write("");';
}
printEmailAddress("fake@mail.com");
?>
