Installation
------------

[](#installation)

[Download a latest package](https://github.com/czproject/phpdepend/releases) or use [Composer](http://getcomposer.org/):

```
composer require czproject/phpdepend

```

PhpDepend requires PHP 8.0 or later and enabled [Tokenizer extension](http://www.php.net/manual/en/book.tokenizer.php) (enabled by default from PHP 4.3.0).

Usage
-----

[](#usage)

```
$phpdepend = new CzProject\PhpDepend\PhpDepend;

// file parsing
$phpdepend->parseFile('MyClass.php');

// code snippet parsing
$source = file_get_contents('MyClass.php');
$phpdepend->parse($source);

// getting result
$phpdepend->getClasses(); // returns list of defined classes, interfaces & traits
$phpdepend->getDependencies(); // returns list of required classes, interfaces & traits
```

Recognized dependencies in PHP code:

- inherited classes (`extends ParentClass`)
- implemented interfaces (`implements InterfaceA, InterfaceB`)
- used traits (`class MyClass { use Trait; }`)
- classes of created instances (`new Object()`)
- static classes (`StaticClass::staticMethod()`, `StaticClass::$staticProperty`)

Ignored dependencies:

- `self::` - `self` means "this class" → useless (no dependency, class is defined in same file)
- `parent::` - parent class is specified in `extends`
- `static::` - `static` is dynamic-`self` → means "this class", parent or descendant (if exists)

Recognized defined classes (output of `$phpdepend->getClasses()`):

- defined classes (`class MyClass`)
- defined interfaces (`interface MyInterface`)
- defined traits (`trait MyTrait`)
