First, the lexer tokenizes the template source code into small pieces for easier processing;; Then, the parser converts the token stream into a meaningful tree of nodes (the Abstract Syntax Tree);; Eventually, the compiler transforms the AST into PHP code. Evaluate the template: It basically means calling the display() method.

Grammar inheritance is also an interesting way to change the behavior. Incomplete hierarchies results in an error message from ANTLR. Grammars in the same file as P are given precendence to those obtained from other files. The.
