base64_encode(openssl_random_pseudo_bytes(32)) issues

As the title suggests I am having an issue with base64_encode(openssl_random_pseudo_bytes(32))

A little background for you, I am using the above to provide a password reset code which is emailed to the user and then used as a hidden input on the reset password form.

I have an issue where + symbols are being removed when using GET to print the reset code into the hidden input field.

For example:

9Y8+Wc6MSSPK8krCBszEdGZJx8v3j9qt/i/tbKBB6z8=

becomes:

9Y8 Wc6MSSPK8krCBszEdGZJx8v3j9qt/i/tbKBB6z8=

So just to go over that once more, I use base64 and openssl to create a string (works perfectly), the user is then emailed a link with this code as GET, IE mywebsite.com/?reset=9Y8+Wc6MSSPK8krCBszEdGZJx8v3j9qt/i/tbKBB6z8=, I then use PHP $_GET['reset'] to echo out the reset code into a hidden input field and this is where my issue is, the + symbol has been replaced with a space and I have no idea why or how to fix it.

Just to add I know how to adjust my code to make a work around for this but I need to understand the actual problem and why this happens.
