How to encode & decode email?

[Freejoy]

I have this:

$email = 'example@somemail.com'; 
echo base64_encode($email);

When I echo it like this:

echo base64_decode($email);

It outputs this:

{��W��g�j)\�

not example@somemail.com

I’m trying to pass it in a url link like this:

$email = base64_decode($_GET['email'];)

What I’m I doing wrong? Thank you

you’re decoding the plain email - but you have to use the return value of base64_encode() for base64_decode()

How do you mean?

How do I get the return value?

[Gandalf]

$encoded = base64_encode($email);
echo base64_decode($encoded);

@Gandalf

$encoded = base64_encode($email);
echo base64_decode($encoded);

You got it! Thanks. Now I can use? $email = base64_decode($_GET['email']);

That will work, as long as you’re passing the encoded email string in your $_GET parameter.

@Freejoy

$email = base64_decode($_GET[‘email’]);

You should sanitize all $_GET variables before using them just in case someone tampered with the value.

$email = filter_var(base64_decode($_GET['email']), FILTER_SANITIZE_EMAIL);
