ast 1.0.3

Extension exposing PHP 7 abstract syntax tree

php-ast exports the AST internally used by PHP 7.
php-ast is significantly faster than PHP-Parser, because the AST construction is implemented in C.
However, php-ast may only parse code that is syntactically valid on the version of PHP it runs on.
