How does the use of different operating systems (Windows vs Linux) affect file path resolution in PHP applications?

When using different operating systems, file path resolution in PHP applications can be affected due to the difference in directory separators. Windows uses backslashes (\) while Linux uses forward slashes (/). To ensure cross-platform compatibility, you can use the PHP built-in DIRECTORY_SEPARATOR constant to dynamically generate file paths. 

// Example of dynamically generating file paths using DIRECTORY_SEPARATOR constant
$filePath = 'path' . DIRECTORY_SEPARATOR . 'to' . DIRECTORY_SEPARATOR . 'file.php';
include $filePath;
