The notices are a consequence of token scope parsing not occurring during the parenthesis of the IF statement, as seen in the verbose output: *** START SCOPE MAP *** Start scope map at 1: T_IF => if Process token 2 []: T_WHITESPACE => Process token 3 []: T_OPEN_PARENTHESIS => ( * skipping parenthesis * Process token 39 []: T_WHITESPACE => Process token 40 []: T_OPEN_CURLY_BRACKET => { => Found scope opener for 1 (T_IF) Process token 41 [opener:40;]: T_WHITESPACE => \n Process token 42 [opener:40;]: T_WHITESPACE => Process token 43 [opener:40;]: T_ECHO => echo Process token 44 [opener:40;]: T_WHITESPACE => Process token 45 [opener:40;]: T_CONSTANT_ENCAPSED_STRING => "foo" Process token 46 [opener:40;]: T_SEMICOLON => ; Process token 47 [opener:40;]: T_WHITESPACE => \n Process token 48 [opener:40;]: T_CLOSE_CURLY_BRACKET => } => Found scope closer for 1 (T_IF) *** END SCOPE MAP *** Removing the notices is easy. Parsing inside the brackets will potentially break a lot of things and needs to be fixed carefully.

The notices were fixed long ago and I don't remember what I was going to try and fix in the tokenizer. No need to keep this open any longer.
