PHP Lexer and Parser Generator?

I know question Lex and Yacc in PHP was asked before but 1 year ago.

Is there any new mature PHP parser generator now? My searches drove me to the following ones, what do you think about them, any others?

  • code.google.com/p/antlrphpruntime/ : The ANTLR PHP version but it seems to be very beta version and I think there is a lot of work to do. The advantage is that I can write the grammar in the ANTLR Works tool.
  • pear.php.net/package/PHP_ParserGenerator/docs/0.1.7/ : I tried but it seems very complicated, to be used with the PHP_LexerGenerator.
  • sourceforge.net/projects/lime-php/ : I didn't try
  • bitbucket.org/wez/lemon-php/downloads : I didn't try
  • bitbucket.org/wez/jlexphp/downloads : I didn't try

[Answer :] Somebody gave me this wonderful link to an old question : Is there an alternative for flex/bison that is usable on 8-bit embedded systems?

This posts allowed me to understand most of the ANTLR code generated. So my choice keeps being the same : ANTLR although the project seems dead. I hope I wont have to alter the code as I would like to keep it maintainable.

I will wait a bit to see if there is another answer otherwise I'll accept your advise to keep using ANTLR

Solution

  • I'd propose to give ANTLR a try. ANTLRWorks might be helpful.

    I wrote an LL(1) parser generator myself in pure PHP, since I wasn't aware of other PHP-based solutions.
