Question

Basically what I want to do is display an email using javascript to bring the parts together and form a complete email address that cannot be visible by email harvesters.

I would like to take an email address eg [e-mail] and break it to:
$variable1 = “info”;
$variable2 = “thiscompany.com”;

All this done in PHP.

Regards,
JB

Try this one before you roll your own (it does a lot more):

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;

}
