README

Runtime method interception and overriding for Laravel applications.

This package allows you to override instance and static methods on a class at runtime by generating a proxy class that delegates to an implementation closure.

Installation

Install the package with Composer:

composer require athwari/laravel-method-overrider

Laravel package auto-discovery is supported, so the service provider and facade are registered automatically.

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=method-overrider-config

The published config file is located at config/method-overrider.php.

Default configuration

return [
    'ignore_final_methods' => true,
];

• ignore_final_methods: when true, final methods are skipped during override generation instead of throwing an exception.

Usage

Use the MethodOverrider facade to override methods on a target class.

Override a method

use Athwari\MethodOverrider\Facades\MethodOverrider;

class TestService
{
    public function greet(string $name): string
    {
        return "Hello {$name}";
    }
}

$service = MethodOverrider::override(
    TestService::class,
    'greet',
    function ($original, $name) {
        return strtoupper($original($name));
    }
);

echo $service->greet('Taylor'); // HELLO TAYLOR

Override multiple methods

$service = MethodOverrider::override(
    TestService::class,
    ['greet', 'nullable'],
    [
        function ($original, $name) {
            return strtoupper($original($name));
        },
        function ($original, $name) {
            return $original($name);
        },
    ]
);

Supported method signatures

The package supports:

• nullable and union parameter types
• variadic parameters
• reference parameters
• static methods
• return types

Final methods are skipped when ignore_final_methods is enabled.

Exceptions

The package throws exceptions for invalid usage:

• Athwari\MethodOverrider\Exceptions\ClassNotFoundException
• Athwari\MethodOverrider\Exceptions\MethodNotFoundException
• Athwari\MethodOverrider\Exceptions\InvalidImplementationException

Testing

Run the test suite with Pest:

composer test
