You should use the fork at php-stubs/generator, which is thanks to @szepeviktor.
PHP Stubs Generator
Use this tool to generate stub declarations for functions, classes, interfaces, and global variables defined in any PHP code. The stubs can subsequently be used to facilitate IDE completion or static analysis via Psalm or potentially other tools. Stub generation is particularly useful for code which mixes definitions with side-effects.
The generator is based on nikic's PHP-Parser, and the code also relies on several Symfony components.

Example
The idea is to turn this:
// source-file-1.php /** * @param string $bar * @return int */ function foo($bar) { return (int) $bar; } /** @var string */ $something = '123abc'; if ($something) { echo foo($something); } // source-file-2.php namespace MyNamespace; class MyClass extends MyParentClass { public function method(): string { return ''; } }
Into this:
// stubs.php namespace { /** * @param string $bar * @return int */ function foo($bar) { } /** @var string */ $something = '123abc'; } namespace MyNamespace { class MyClass extends MyParentClass { public function method(): string { } } }
Command Line Usage
To install:
composer global require giacocorsiglia/stubs-generator
To get the pretty-printed stubs for all the PHP files in a directory:
generate-stubs /path/to/my-library
You may also pass multiple directories, or filenames, separated by spaces. All stubs will be concatenated in the output.
To write the stubs to a file (and see a few statistics in the stdout):
generate-stubs /path/to/my-library --out=/path/to/output.php
For the complete set of command line options:
generate-stubs --help
Usage in PHP
To install:
composer require giacocorsiglia/stubs-generator
Simple Example
// You'll need the Composer Autoloader. require 'vendor/autoload.php'; // You may alias the classnames for convenience. use StubsGenerator\{StubsGenerator, Finder}; // First, instantiate a `StubsGenerator\StubsGenerator`. $generator = new StubsGenerator(); // Then, create a `StubsGenerator\Finder` which contains // the set of files you wish to generate stubs for. $finder = Finder::create()->in('/path/to/my-library/'); // Now you may use the `StubsGenerator::generate()` method, // which will return a `StubsGenerator\Result` instance. $result = $generator->generate($finder); // You can use the `Result` instance to pretty-print the stubs. echo $result->prettyPrint(); // You can also use it to retrieve the PHP-Parser nodes // that represent the generated stub declarations. $stmts = $result->getStubStmts();
Additional Features
You can restrict the set of symbol types for which stubs are generated:
// This will only generate stubs for function declarations. $generator = new StubsGenerator(StubsGenerator::FUNCTIONS); // This will only generate stubs for class or interface declarations. $generator = new StubsGenerator(StubsGenerator::CLASSES | StubsGenerator::INTERFACES);
The set of symbol types are:
StubsGenerator::FUNCTIONS
: Function declarations.StubsGenerator::CLASSES
: Class declarations.StubsGenerator::TRAITS
: Trait declarations.StubsGenerator::INTERFACES
: Interface declarations.StubsGenerator::DOCUMENTED_GLOBALS
: Global variables, but only those with a doc comment.StubsGenerator::UNDOCUMENTED_GLOBALS
: Global variable, but only those without a doc comment.StubsGenerator::GLOBALS
: Shortcut to include both documented and undocumented global variables.StubsGenerator::DEFAULT
: Shortcut to include everything except undocumented global variables.StubsGenerator::ALL
: Shortcut to include everything.
TODO
- Add support for constants declared with
const
. - Add support for constants declared with
define()
.- Consider parsing function and method bodies for these declarations.
