Sameer Borate's Blog:
Building a simple Parser and Lexer in PHP
November 17, 2011 @ 11:57:59

In a new post to his blog Sameer Borate shows how to create a lexer and parser in PHP to work directly with the tokens of a PHP script.

After looking around for a while [for a good resource on compilers] I settled for Terence Parr's Language Implementation Patterns. This is exactly what I needed - bit sized patterns on compiler and parser design with working code. The book provides a recipe style approach, gradually moving from simple to complex compiler/parser design issues. As I primarily work with PHP, I thought of porting some code to PHP to see how it works.

He shows examples using his custom tool to show a basic lexer output for a list and a complete listing of the code involved. Ultimately, though, he finds that PHP isn't overly suited to the task - anything more than his simple example could be more trouble than it's worth.
