In PHP, what are some best practices for handling file paths in classes that inherit from a base class?

When working with classes that inherit from a base class in PHP, it's important to handle file paths consistently to avoid issues with file operations. One best practice is to define a base path property in the base class and use it to construct file paths in child classes. This ensures that file paths are consistent across all classes and makes it easier to update the base path if needed. 

class BaseClass {
    protected $basePath = '/path/to/files/';

    protected function constructFilePath($fileName) {
        return $this->basePath . $fileName;
    }
}

class ChildClass extends BaseClass {
    public function readFile($fileName) {
        $filePath = $this->constructFilePath($fileName);
        // code to read file at $filePath
    }

    public function writeFile($fileName, $data) {
        $filePath = $this->constructFilePath($fileName);
        // code to write $data to file at $filePath
    }
}
