+PHP Parser
+==========
+
+[![Coverage Status](https://coveralls.io/repos/github/nikic/PHP-Parser/badge.svg?branch=master)](https://coveralls.io/github/nikic/PHP-Parser?branch=master)
+
+This is a PHP 5.2 to PHP 8.0 parser written in PHP. Its purpose is to simplify static code analysis and
+manipulation.
+
+[**Documentation for version 4.x**][doc_master] (stable; for running on PHP >= 7.0; for parsing PHP 5.2 to PHP 8.0).
+
+[Documentation for version 3.x][doc_3_x] (unsupported; for running on PHP >= 5.5; for parsing PHP 5.2 to PHP 7.2).
+
+Features
+--------
+
+The main features provided by this library are:
+
+ * Parsing PHP 5, PHP 7, and PHP 8 code into an abstract syntax tree (AST).
+   * Invalid code can be parsed into a partial AST.
+   * The AST contains accurate location information.
+ * Dumping the AST in human-readable form.
+ * Converting an AST back to PHP code.
+   * Experimental: Formatting can be preserved for partially changed ASTs.
+ * Infrastructure to traverse and modify ASTs.
+ * Resolution of namespaced names.
+ * Evaluation of constant expressions.
+ * Builders to simplify AST construction for code generation.
+ * Converting an AST into JSON and back.
+
+Quick Start
+-----------
+
+Install the library using [composer](https://getcomposer.org):
+
+    php composer.phar require nikic/php-parser
+
+Parse some PHP code into an AST and dump the result in human-readable form:
+
+```php
+<?php
+use PhpParser\Error;
+use PhpParser\NodeDumper;
+use PhpParser\ParserFactory;
+
+$code = <<<'CODE'
+<?php
+
+function test($foo)
+{
+    var_dump($foo);
+}
+CODE;
+
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+try {
+    $ast = $parser->parse($code);
+} catch (Error $error) {
+    echo "Parse error: {$error->getMessage()}\n";
+    return;
+}
+
+$dumper = new NodeDumper;
+echo $dumper->dump($ast) . "\n";
+```
+
+This dumps an AST looking something like this:
+
+```
+array(
+    0: Stmt_Function(
+        byRef: false
+        name: Identifier(
+            name: test
+        )
+        params: array(
+            0: Param(
+                type: null
+                byRef: false
+                variadic: false
+                var: Expr_Variable(
+                    name: foo
+                )
+                default: null
+            )
+        )
+        returnType: null
+        stmts: array(
+            0: Stmt_Expression(
+                expr: Expr_FuncCall(
+                    name: Name(
+                        parts: array(
+                            0: var_dump
+                        )
+                    )
+                    args: array(
+                        0: Arg(
+                            value: Expr_Variable(
+                                name: foo
+                            )
+                            byRef: false
+                            unpack: false
+                        )
+                    )
+                )
+            )
+        )
+    )
+)
+```
+
+Let's traverse the AST and perform some kind of modification. For example, drop all function bodies:
+
+```php
+use PhpParser\Node;
+use PhpParser\Node\Stmt\Function_;
+use PhpParser\NodeTraverser;
+use PhpParser\NodeVisitorAbstract;
+
+$traverser = new NodeTraverser();
+$traverser->addVisitor(new class extends NodeVisitorAbstract {
+    public function enterNode(Node $node) {
+        if ($node instanceof Function_) {
+            // Clean out the function body
+            $node->stmts = [];
+        }
+    }
+});
+
+$ast = $traverser->traverse($ast);
+echo $dumper->dump($ast) . "\n";
+```
+
+This gives us an AST where the `Function_::$stmts` are empty:
+
+```
+array(
+    0: Stmt_Function(
+        byRef: false
+        name: Identifier(
+            name: test
+        )
+        params: array(
+            0: Param(
+                type: null
+                byRef: false
+                variadic: false
+                var: Expr_Variable(
+                    name: foo
+                )
+                default: null
+            )
+        )
+        returnType: null
+        stmts: array(
+        )
+    )
+)
+```
+
+Finally, we can convert the new AST back to PHP code:
+
+```php
+use PhpParser\PrettyPrinter;
+
+$prettyPrinter = new PrettyPrinter\Standard;
+echo $prettyPrinter->prettyPrintFile($ast);
+```
+
+This gives us our original code, minus the `var_dump()` call inside the function:
+
+```php
+<?php
+
+function test($foo)
+{
+}
+```

+What do all those files mean?
+=============================
+
+ * `php5.y`:             PHP 5 grammar written in a pseudo language
+ * `php7.y`:             PHP 7 grammar written in a pseudo language
+ * `tokens.y`:           Tokens definition shared between PHP 5 and PHP 7 grammars
+ * `parser.template`:    A `kmyacc` parser prototype file for PHP
+ * `tokens.template`:    A `kmyacc` prototype file for the `Tokens` class
+ * `rebuildParsers.php`: Preprocesses the grammar and builds the parser using `kmyacc`
+
+.phpy pseudo language
+=====================
+
+The `.y` file is a normal grammar in `kmyacc` (`yacc`) style, with some transformations
+applied to it:
+
+ * Nodes are created using the syntax `Name[..., ...]`. This is transformed into
+   `new Name(..., ..., attributes())`
+ * Some function-like constructs are resolved (see `rebuildParsers.php` for a list)
+
+Building the parser
+===================
+
+Run `php grammar/rebuildParsers.php` to rebuild the parsers. Additional options:
+
+ * The `KMYACC` environment variable can be used to specify an alternative `kmyacc` binary.
+   By default the `phpyacc` dev dependency will be used. To use the original `kmyacc`, you
+   need to compile [moriyoshi's fork](https://github.com/moriyoshi/kmyacc-forked).
+ * The `--debug` option enables emission of debug symbols and creates the `y.output` file.
