Email ASCII encode helper

For basic spam protection I did set up a helper that encodes email addresses in ASCII. [code] <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); /**

• Encodes (ASCII) email addresses for basic spam protection
• @access public
• @param string - email address
• @param string
• @param bool
• @param string - name of css class
• @return string
• @author Luckyfella73 */

/**

• Usage Exaples:

• returns pure email address ASCII encoded:

• echo (encode_email('[email protected]'));

• returns email address ASCII encoded with "mailto: link" and defined anchor text:

• echo (encode_email('[email protected]','John Doe','TRUE'));

• returns email address ASCII encoded with mailto: link, defined anchor text and css class for tag:

• echo (encode_email('[email protected]','John Doe','TRUE','my-link-style')); */ if ( ! function_exists('encode_email')) { function encode_email($email, $anchor_text = '', $mailto = FALSE, $css = '') { $email = trim($email); $anchor_text = trim($anchor_text); $css = trim($css);

   if ($email === '')
   {
       return '';
   }
  
   $email_encoded = '';
   for ($i=0; $i < strlen($email); $i++)
   {
       $email_encoded .= '&#'.ord(substr($email,$i)).';';
   }
  
   if ($anchor_text === '')
   {
       $anchor_text = $email_encoded;
   }
  
   if ($mailto === TRUE)
   {
       if (strlen($css) > 1)
       {
           $css = ' class="'.$css.'" ';
       }
       return '<a href="milto'.$email_encoded.'">'.$anchor_text.'</a>'. "\n";
   }
   else
   {
       return $email_encoded;
   }
  

  } }
