This is an adaptation of lemon that optionally emits PHP code to implement a

parser for the grammar described in a .y file.

Usage:

 cc -o lemon lemon.c

 lemon -lPHP my.y

This will output my.php, which contains a PHP class that implements your parser.

Usage is along the lines of:

$P = new ParseParser();

$S = new Yylex(); // you can get one of these using the JLexPHP package

while ($t = $S->yylex()) {

	$P->Parse($t->type, $t);

}

$P->Parse(0);

Enjoy!
