How can the use of backslashes in server paths affect PHP functionality?

When using backslashes in server paths in PHP, it can cause issues because backslashes are typically used as escape characters in PHP. To avoid problems, it's recommended to use forward slashes in server paths instead of backslashes. This ensures that the paths are correctly interpreted by PHP.

// Incorrect usage of backslashes in server path
$serverPath = 'C:\xampp\htdocs\project\file.php';

// Corrected server path using forward slashes
$serverPath = 'C:/xampp/htdocs/project/file.php';
