[RESOLVED] undefined variable?!?

[rupertbj]

I get the following error:

Notice: Undefined variable: encrypted_email in /home/fhlinux160/i/il-palazzetto.com/user/htdocs/obfuscate.php on line 6

Which is from the following code:

<?php
//Email Obfuscator
    $designMail = "[e-mail]";
    $len = strlen($designMail);
    for ($i=0;$i<$len;$i++)
    $encrypted_email .= "&#" . ord($designMail[$i]);
//  echo $encrypted_email;
?>

As far as I can see the variable is defined? It certainly works on other sites that I have, but with one site (hosted with the same hosting company, it does not seem to work?

Any ideas?

Many thanks,

Rupert

Let's expand the .= operator:

$encrypted_email = $encrypted_email . "&#" . ord($designMail[$i]);

Whoops, you are concatenating $encrypted_email with two strings, but $encrypted_email does not exist!

The solution is to just use assignment:

$encrypted_email = "&#" . ord($designMail[$i]);

I amended as suggested, but I get the same error?

Scratch that.....it does work now - cacheing problem before!
Many thanks!

Sorry, I did not interpret your code correctly. Please indent your code properly next time.

Here's your current code with some indentation and braces added for emphasis:

<?php
//Email Obfuscator
$designMail = "[e-mail]";
$len = strlen($designMail);
for ($i=0;$i<$len;$i++) {
    $encrypted_email .= "&#" . ord($designMail[$i]);
}
//  echo $encrypted_email;
?>

It is clear that the problem I outlined still holds. So, what you need to do is to start off with an empty string, upon which each iteration of the loop will append to that string:

<?php
//Email Obfuscator
$designMail = "[e-mail]";
$len = strlen($designMail);
$encrypted_email = '';
for ($i=0;$i<$len;$i++) {
    $encrypted_email .= "&#" . ord($designMail[$i]);
}
//  echo $encrypted_email;
?>

@ Laserlight - thanks! I just noticed the earlier one was just producing an "m"!!
This one works a treat.
I'll work on my indentation.
