Hello!

I'm trying to obfuscate and "linkify" mail addresses in a text with the  
following modifier:

function smarty_modifier_mail_escape($string)
{
      return  
preg_replace_callback("/[_a-z0-9.A-Z]+@[-a-z0-9.A- 
Z]+/","escape_mail",$string);
}

function escape_mail($text)
  {
      echo "escape_mail called";//<-- for debugging purposes, to test if  
the func is called
      $text=$text[0];
      for($i=0;$i<strlen($text);$i++)
      {
          $mailto.="&#".ord($text[$i]).";";
      }
      return "<a  
href=\"&#109;&#97;&#105;&#108;&#116;&#111;&#58;$mailto\">$mailto</a>";
  }

The two functions are in the same file but  escape_mail doesn't get  
called (Smarty 2.3, PHP 4.1). What am I doing wrong?

Is there another way to accomplish the obfuscation of email adresses  
that are mingled with normal text?

With best regards

Gabriel Birke
