How can one ensure correct addressing of files in PHP to prevent issues with file access?

When addressing files in PHP, it is important to use the correct file paths to prevent issues with file access. To ensure correct addressing, you can use the `__DIR__` magic constant to get the absolute path of the current file and then concatenate it with the relative path of the file you want to access. This method helps in creating a reliable and consistent file addressing system in your PHP code. 

// Example of correct file addressing in PHP
$filePath = __DIR__ . '/relative/path/to/file.txt';
$fileContent = file_get_contents($filePath);

// Use $filePath variable to access the file content or perform other file operations
