the code property graph is a point that can use in the code static analysis, and it can use the AST, CFG, and PDG in one graph, it can also use in the detecting vulnerability in the PHP. it would be good at doing that.
At first, you must know why to use this graph, for example, why use PDG, what the difference between PDG and CFG?

samely, the PDG and CFG maybe have the same node, as a statement.
