**composer-attribute-collector** is a [Composer](https://getcomposer.org/) plugin designed to effectively *discover* PHP 8 attribute targets, and later retrieve them at near zero cost, without runtime reflection. After the autoloader dump, it collects attributes and generates a static file for fast access. This provides a convenient way to *discover* attribute-backed classes, methods, or properties—ideal for codebase analysis. (For known targets, traditional reflection remains an option.)

#### Features

[](#features)

- Zero configuration
- No reflection in the generated file
- Might improve performance
- No dependency (except Composer of course)
- A single interface to get attribute targets: classes, methods, and properties
- Can cache discoveries to speed up consecutive runs.

Note

Currently, the plugin supports class, method, property, and parameter targets. You're welcome to [contribute](CONTRIBUTING.md) if you're interested in expending its support.

Warning

Attributes used on functions are ignored at this time.

#### Usage

[](#usage)

The following example demonstrates how targets and their attributes can be retrieved:
