Email ASCII encode helper

World Wide Web Server edited this page Jul 4, 2012 · 4 revisions

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;
     }
    

    } }
