Hi!
I'm looking for the PHP 5 grammar specification. I'm studying the
possibility of implementing an abstract interpretation tool with flex/bison
in order to find security vulnerabilities (Injection vulnerabilities, XSS)
in the code in a static manner. I know Pixy but I would like to study
another possibility.
Where I can find the grammar? What do you think about this idea?
