Article Introduction：There are three solutions to prevent the display of directory lists: 1. Use the .htaccess file (for Apache), add the Options-Indexes command in the target directory to prevent the display of directory contents; 2. Modify the server configuration file (general practice), make sure Options does not contain Indexes in Apache, add autoindexoff in Nginx; and restart the service; 3. Put a blank index file and place the index.html or index.php file in the directory to make the server load the file first and avoid displaying the directory contents. These three methods can be selected and used according to permissions and environment, and can effectively prevent the directory content from being listed.

Article Introduction：Install PHPUnit and configure the project environment; 2. Create a test directory structure and correspond to the source code; 3. Write independent test cases and use assertions to verify the results; 4. Use mock objects to isolate external dependencies; 5. Run tests frequently to ensure code quality. First, install PHPUnit through Composer and configure phpunit.xml file. Then create the tests directory to store the test class. Each test class inherits TestCase and writes a method starting with test for testing. Use assertEquals and other assertions to verify the correctness of the logic. Use createMock to simulate behavior for external dependencies. Finally, execute vendor/bin/phpunit commands regularly.

Article Introduction：PHP's automatic loading methods include PSR-0, PSR-4, classmap and files. The core purpose is to implement automatic loading of classes without manually introducing files. 1. PSR-0 is an early standard, and automatically loads through class name and file path mapping, but because the naming specifications are strict and the support for underscores as directory separators have been rarely used; 2. PSR-4 is a modern standard, which adopts a more concise namespace and directory mapping method, allowing a namespace to correspond to multiple directories and does not support underscore separation, becoming the mainstream choice; 3. classmap generates a static mapping table of class names and paths by scanning the specified directory, which is suitable for legacy code that does not follow the PSR specification, but new files need to be regenerated and large directories

Article Introduction：Core points Drupal 8's ConfigFormBase class provides additional functionality to interact with the configuration system, allowing tools to convert forms to stored values. This can be done by replacing the extension class with ConfigFormBase and making the necessary changes in the form. The configuration in Drupal 8 is stored in a YAML file and can be changed through the UI for deployment across different sites. The service container in Drupal 8 allows the creation of a service, that is, a PHP class that performs global operations, and registers it into the service container for access. Dependency injection is used to pass objects to other objects, ensuring decoupling. You can create de in the root directory of the module
