PHP encrypts your E-mail address and generates the javascript that decrypts it. Most bots and spiders can't execute javascript and that is what makes this work.

Copy this code and paste it in your HTML
  1. <?php
  2. function hide_email($email) { $character_set = '+-.0123456789@ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz'; $key = str_shuffle($character_set); $cipher_text = ''; $id = 'e'.rand(1,999999999); for ($i=0;$i<strlen($email);$i+=1) $cipher_text.= $key[strpos($character_set,$email[$i])]; $script = 'var a="'.$key.'";var b=a.split("").sort().join("");var c="'.$cipher_text.'";var d="";'; $script.= 'for(var e=0;e<c.length;e++)d+=b.charAt(a.indexOf(c.charAt(e)));'; $script.= 'document.getElementById("'.$id.'").innerHTML="<a href=\\"mailto:"+d+"\\">"+d+"</a>"'; $script = "eval(\"".str_replace(array("\\",'"'),array("\\\\",'\"'), $script)."\")"; $script = '<script type="text/javascript">/*<![CDATA[*/'.$script.'/*]]>*/</script>'; return '<span id="'.$id.'">[javascript protected email address]</span>'.$script; }
  3. ?>
  5. //////////// USAGE ////////////
  7. This is the PHP code you write where you want the E-mail address on your web page.
  9. <?php echo hide_email('[email protected]'); ?>
  11. This is what the E-mail address will look like for the visitor of your web page.
  13. <span id="e401621484">[javascript protected email address]</span><script type="text/javascript">/*<![CDATA[*/eval("var a=\"4taVs.lchvwRT8DJFqzfejbE5QXM_-irgWkSHAPmU+d1I32xKZByoC@GYNL7pnu90O6\";var b=a.split(\"\").sort().join(\"\");var c=\"p37p8p37pa1GC\";var d=\"\";for(var e=0;e<c.length;e++)d+=b.charAt(a.indexOf(c.charAt(e)));document.getElementById(\"e401621484\").innerHTML=\"<a href=\\\"mailto:\"+d+\"\\\">\"+d+\"</a>\"")/*]]>*/</script>
