PHP - Errors On Line 1 Every Time

I keep getting this error and I don't know what's wrong. My mysql class is fine, but then the user class keeps getting the error:
Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home2/-/public_html/special/classes/users.php on line 1
Any change I make, it's always an error on line 1.
