What are the advantages and disadvantages of using __DIR__ versus hardcoded paths in PHP file operations?

When working with file operations in PHP, using __DIR__ to dynamically get the current directory path is generally preferred over hardcoded paths. This approach makes the code more portable and reduces the risk of errors when moving the code to different directories or servers. However, hardcoded paths can sometimes be necessary in certain situations where the directory structure is fixed and won't change. 

// Using __DIR__ to get the current directory path
$file_path = __DIR__ . '/file.txt';

// Using a hardcoded path
$file_path = '/path/to/file.txt';
