Php Attribute Reader Laravel Package

PHP 8.0 introduced attributes, but the reflection API to actually read them is verbose and awkward. Want to check if a class has a specific attribute? That's four lines. Want to find every occurrence of an attribute across a class, its methods, properties, constants, and parameters? That's 40+ lines of nested foreach loops.

This package gives you a clean, static API instead:

use Spatie\Attributes\Attributes;

// Get a single attribute from a class
$route = Attributes::get(MyController::class, Route::class);

// Check if a class has an attribute
Attributes::has(MyController::class, Route::class); // true

// Read from methods, properties, constants, parameters
Attributes::onMethod(MyController::class, 'index', Route::class);
Attributes::onProperty(User::class, 'email', Column::class);
Attributes::onConstant(Status::class, 'ACTIVE', Label::class);
Attributes::onParameter(MyController::class, 'show', 'id', FromRoute::class);

// Find an attribute everywhere in a class at once
$results = Attributes::find(MyForm::class, Validate::class);

foreach ($results as $result) {
    $result->attribute; // The instantiated attribute
    $result->target;    // The Reflection object
    $result->name;      // e.g. 'email', 'handle.request'
}

Every method returns instantiated attribute objects, missing targets return null instead of throwing exceptions, and child attributes are matched automatically.
