title: EBNF grammar definitions for PHP?
body: <p>I am wondering if someone has compiled an EBNF for PHP somewhere. I found both <a href="http://www.icosaedro.it/articoli/php-syntax.html" rel="noreferrer">this site</a> and <a href="http://marc.info/?l=php-internals&amp;m=129389890703226&amp;w=2" rel="noreferrer">this site</a>. Both seem like they are incomplete, though. <a href="https://stackoverflow.com/questions/4680119/php-language-specification">This question is very similar</a>, but it's a year old. I would like to know if there has been any progress made.</p>
