Is it necessary to differentiate between directory separators in PHP for different operating systems, or can a universal approach be used?

In PHP, it is necessary to differentiate between directory separators for different operating systems to ensure cross-platform compatibility. This can be achieved by using the DIRECTORY_SEPARATOR constant, which automatically selects the appropriate separator based on the current operating system. By using this constant in file paths, you can write code that works seamlessly on Windows, Linux, and macOS. 

// Using DIRECTORY_SEPARATOR to handle directory separators
$path = 'path' . DIRECTORY_SEPARATOR . 'to' . DIRECTORY_SEPARATOR . 'file.txt';
echo $path;
