What are common issues when migrating PHP scripts from Windows to Debian?

One common issue when migrating PHP scripts from Windows to Debian is the difference in file path separators. Windows uses backslashes (\) while Debian uses forward slashes (/). To solve this issue, you can use the PHP built-in constant DIRECTORY_SEPARATOR to ensure cross-platform compatibility.

// Replace backslashes with DIRECTORY_SEPARATOR
$path = str_replace('\\', DIRECTORY_SEPARATOR, $path);
