What are the implications of using escape sequences, such as backslashes, in file paths within PHP scripts?

When using escape sequences like backslashes in file paths within PHP scripts, it can lead to errors or unexpected behavior because backslashes are used as escape characters in PHP. To avoid this issue, it's recommended to use forward slashes (/) in file paths instead of backslashes.

// Incorrect usage of backslashes in file path
$file_path = "C:\xampp\htdocs\example\file.txt";

// Correct usage of forward slashes in file path
$file_path = "C:/xampp/htdocs/example/file.txt";
