PHP-Parser 5.0.0-alpha1

See UPGRADE-5.0 for detailed migration instructions.

Changed

• PHP 7.1 is now required to run PHP-Parser.
• Formatting of the standard pretty printer has been adjusted to match PSR-12 more closely.
• The internal token representation now uses a PhpParser\Token class, which is compatible with PHP 8 token representation (PhpToken).
• Destructuring is now always represented using Expr\List_ nodes, even if it uses [] syntax.
• Renamed a number of node classes, and moved things that were not real expressions/statements outside the Expr/Stmt hierarchy. Compatibility shims for the old names have been retained.

Added

• Added PhpVersion class, which is accepted in a number of places (e.g. ParserFactory, Parser, Lexer, PrettyPrinter) and gives more precise control over the PHP version being targeted.
• Added PHP 8 parser though it only differs from the PHP 7 parser in concatenation precedence.
• Added Parser::getLexer() method.
• Added a Modifiers class, as a replacement for Stmt\Class_::MODIFIER_*.
• Added support for returning an array or REMOVE_NODE from NodeVisitor::enterNode().

Removed

• The PHP 5 parser has been removed. The PHP 7 parser has been adjusted to deal with PHP 5 code more gracefully.
