Typos:
- missing line here
- missing line before method
- method's `{` should be on new line
- after comment `//` make a space
- `$savedPositon = $tokenizer->position;` \n $tokenizer->position--;` equals to `$savedPositon = $tokenizer->position--;`, but much better is imo `$tokenizer->position -= 1;`
- we use upercase boolean expressions. TRUE.
