I am looking for a PHP script that can automatically manage the addition, update, and deletion of components within a Laravel project, based on instructions specified in a JSON file. This functionality is intended to dynamically modify models, controllers, and migrations within the project. I plan to use `nikic/php-parser` for parsing PHP code since it's highly flexible and already integrated into Laravel.

The script will be part of a directory named `Deployer`, located at the root of the Laravel project. This directory will contain all necessary files for the operation of this script.

**Functional Requirements:**

The script should be able to:

- **For Models:**
  - Add, update, or remove import packages.
  - Add, update, or remove traits.
  - Add, update, or remove methods.

- **For Controllers:**
  - Add, update, or remove import packages.
  - Add, update, or remove traits.
  - Add, update, or remove methods.

- **For Migrations:**
  - Add, update, or remove columns.

**Development Process:**

1. **Create a JSON Template:** First, we need to establish a JSON template that encapsulates all modifications to be made. This template will guide the script on what changes to apply to the project files. Example of a JSON structure: (Please i want you to continue the JSON for a more complete based on my requirement and adjust if needed)

```json
{
  "updates": [
    {
      "model": "Brand",
      "action": "add",
      "methods": [
        {
          "name": "setAuthorAttribute",
          "content": "$this->attributes['author'] = Auth::user()->name;"
        },
        {
          "name": "getCreatedAtFormattedAttribute",
          "content": "return date('Y-m-d H:i:s', strtotime($this->created_at));"
        }
      ]
    }
  ]
}
```

### 2. Parsing the JSON Template:

Upon successfully loading and decoding the JSON template, our script should iterate through each instruction defined within. These instructions dictate the actions to be taken on the models, controllers, and migrations. The script would need logic to handle different types of actions (add, update, remove) and components (methods, traits, import packages, columns) as specified.

### 3. Updating Models, Controllers, and Migrations:

For each component (models, controllers, migrations), the script identifies the specific file related to the instruction and uses `nikic/php-parser` to parse PHP code.

- **Models & Controllers:**
  - **Import Packages/Traits:**  Depending on the action, it will add or update existing or delete use statements at the beginning of the file.
  - **Methods:** Depending on the action, it will insert new methods, update existing ones by matching method names, or remove them entirely.
  - The script ensures that it maintains the correct syntax and formatting to keep the code functional and readable.

- **Migrations:**
  - **Columns:** For migrations, the script adjusts table blueprints to add, modify, or drop columns as instructed. This might involve more nuanced handling to identify the correct migration file based on naming conventions or content inspection.

### 4. Error Handling and Validation:

Throughout this process, robust error handling is critical. This includes validating the JSON instructions, ensuring files exist before attempting modifications, and verifying the success of the PHP code parsing and modification. The script should log actions taken and any errors encountered, providing a clear trail of what changes were made or attempted.

### 5. Testing and Integration:

After the script is developed, it's important to thoroughly test it in a controlled environment. This might involve creating a test Laravel project and a set of JSON instructions designed to cover all possible actions and edge cases. Ensuring the script performs as expected across different scenarios is crucial before integrating it into any live projects.

### 6. Automation and Continuous Integration:

Finally, consider integrating this script into your development workflow or CI/CD pipeline. This automation can ensure that model, controller, and migration modifications are seamlessly managed through JSON instructions, making the development process more efficient and reducing the risk of manual errors.
