I've had good luck so far with this:
/**
* emailEncode
*
* Spits out email addresses using HTML entities instead of the actual
* characters as an attempt to prevent spam to these addresses.
* Searches for email addresses, links them, and encodes them.
*
* @param $x The content that contains the email address(es)
* @result Returns the input with addresses encoded
*/
function emailEncode($x){
~ $pattern='/([a-z][a-z0-9_.-\/\%]*@[^\s\"\)\?<>]+\.[a-z]{2,6})/i';
~ $search=array();
~ $replace=array();
~ if(preg_match_all($pattern,$x,$matches)){
~ if(isset($matches[0])){
~ // There should be at least one match from the string.
~ for($i=0;$i<count($matches[0]);$i++){
~ $search[]=$matches[0][$i];
~ $str='';
~ for($j=0;$j<strlen($matches[0][$i]);++$j){
~ $str.='&#'.ord($matches[0][$i]{$j}).';';
~ }
~ $replace[]='<a href="mailto:'.$str.'">'.$str.'</a>';
~ }
~ }
~ }
~ return str_replace($search,$replace,$x);
}
I just pass the entire content block into it... It translates
"spam@koivi.com" to
"spam@koivi.com"
