How can the use of double backslashes instead of single backslashes impact PHP code?

Using double backslashes instead of single backslashes in PHP code can cause syntax errors or unexpected behavior because double backslashes are used to escape characters in PHP strings. To avoid this issue, always use single backslashes when escaping characters in PHP code.

// Incorrect usage of double backslashes
$path = "C:\\xampp\\htdocs\\index.php";

// Correct usage of single backslashes
$path = "C:\xampp\htdocs\index.php";
