There seem to be no syntax errors. Why do you assume there is an error? Do you get any messages? Is the result not what you expected? What is different from what you expected?

[toxicandy]

I agree with Broj1, what are the error codes you are getting? As far as syntax errors I really only found one on line 97 you have !== where it is supposed to be !=. But becasue you can't use !== that may be giving you some fault.

[broj1]

Just a note @toxicandy: !== is also a valid syntax. In PHP you can use three comparison operators in place of two which means you want to compare both values and types. See this link. So line

if($pass1 !== $pass2)

essentially says: if $pass1 is not equal to $pass2 and/or $pass1 is not the of same type as $pass2 then...

Consider the following code:

$pass1 = 1234;
$pass2 = '1234';
if($pass1 !== $pass2) // returns true
if($pass1 != $pass2) // returns false

But form fields always return strings so above test is a bit pointless.
