[Resolved] Javascript to PHP

[DeadFly]

I'm trying to covert a piece of javascript code into PHP function, but I'm not totally sure how to do it . . .
Here is the javascript version:

<SCRIPT LANGUAGE="JavaScript">
<!-- Hide code from older browsers
function encodeEmail() {
var regEmail = document.ENCODER.regEmail.value.toLowerCase()
var codeEmail = ""
if (regEmail == "") {
        alert("Please enter your regular e-mail address.")
}
else {
        var regLength = regEmail.length
        for (i = 0; i < regLength; i++) {
                var charNum = "000"
                var curChar = regEmail.charAt(i)
                if (curChar == "a") {
                        charNum = "097"
                }
                if (curChar == "b") {
                        charNum = "098"
                }
                if (curChar == "c") {
                        charNum = "099"
                }
                if (curChar == "d") {
                        charNum = "100"
                }
                if (curChar == "e") {
                        charNum = "101"
                }
                if (curChar == "f") {
                        charNum = "102"
                }
                if (curChar == "g") {

Does anyone know what would be the easiest way to go about this conversion process ?

[DeadFly]

Figured it out . . .

function emailenc($e){
	$e = strtolower($e);
	$trans = array(
		"." => ".","&" => "&"," " => " ","_" => "_","-" => "-",
		"@" => "@","a" => "a","b" => "&#098","c" => "c","d" => "d",
		"e" => "e","f" => "f","g" => "g","h" => "h","i" => "i",
		"j" => "j","k" => "k","l" => "l","m" => "m","n" => "n",
		"o" => "o","p" => "p","q" => "q","r" => "r","s" => "s",
		"t" => "t","u" => "u","v" => "v","w" => "w","x" => "x",
		"y" => "y","z" => "z",		
	);
	$e=strtr($e, $trans);
    return $e;        

} ///// End of function

It will encode email address' so that bots cannot pick them up and spam 'em.

To encode all possible chars you can use this:

$email = "[e-mail]";

function email_encode($e) {
  $s = '';
  for( $i=0; $i<strlen($e); $i++ ) {
    $s .= '&#'.ord($e[$i]).';';
  }
  return $s;
}

echo '<a href="mailto:'.email_encode($email).'">asd</a>';

This is more elegantly 🙂

Thank you !
That's awesome !

This is a nice piece of code, are you sure the bots aren't wise to this approach?
