A PHP base library providing an abstract lexer for building Top-Down, Recursive Descent Parsers. It tokenizes input strings and is used internally by Doctrine Annotations and Doctrine ORM's DQL parser.

Use cases

• write a custom lexer for a DSL in PHP
• tokenize input strings for a recursive descent parser
• build a query language parser like DQL
• parse annotation syntax in PHP
• walk a string token by token with lookahead

When to choose

• you are building a top-down or recursive descent parser in PHP
• you need a small, battle-tested tokenizer base class
• you are already in the Doctrine ecosystem (ORM, Annotations)

When to avoid

• you need a full parser generator or grammar tool (use ANTLR or similar)
• you need high-performance lexing outside PHP
• you want a ready-made parser for an existing format
