How does PHP handle file paths differently on Windows and Linux systems?

PHP handles file paths differently on Windows and Linux systems due to the difference in directory separators. Windows uses backslashes (\) while Linux uses forward slashes (/). To ensure cross-platform compatibility, it is recommended to use the DIRECTORY_SEPARATOR constant in PHP when dealing with file paths. 

// Example of handling file paths in a cross-platform way
$file = 'example' . DIRECTORY_SEPARATOR . 'file.txt';
echo $file;
