What can it parse?
------------------
The parser uses a PHP 5.6 compliant grammar, which is backwards compatible with all PHP version from PHP 5.2
upwards (and maybe older).
The parser supports parsing PHP 5.2-5.6 and PHP 7.
As the parser is based on the tokens returned by `token_get_all` (which is only able to lex the PHP
version it runs on), additionally a wrapper for emulating new tokens from 5.3, 5.4, 5.5 and 5.6 is provided.
This allows to parse PHP 5.6 source code running on PHP 5.3, for example. This emulation is very hacky and not
perfect, but it should work well on any sane code.
