I would like to propose introducing a PHP target and runtime.


Is anyone interested in joining me to implement a PHP target?

Hello Marcos Passos,

I did it for PHP 7.2.

I have used the ANTLR4-runtime C++ target to phpize the library.

<!DOCTYPE html><?xml-stylesheet href="antlr.css" ?><?php
$text = <<<ANTLR
grammar Calculator;

NUMBER: [0-9]+;
WS : [ \\t\\r\\n]+ -> skip ; // notice the antislash in hereDoc

expr
    : sum=(a=expr '+' b=expr)
    | sub=(a=expr '-' b=expr)
    | mul=(a=expr '*' b=expr)
    | div=(a=expr '/' b=expr)
    | fac=('(' a=expr ')')
    | num=(a=NUMBER)
    ;
ANTLR;

$doc = new ANTLRDocument(); // By default the ANTLRDocument use the antlr4 grammar. Use ANTLRImplementation to select parser
$doc->load($text);
$xml = $doc->saveHTML();// $doc->saveJAVA(); ... $doc->saveCPP();

// output expected :
