What are the potential pitfalls of using backslashes (\) instead of forward slashes (/) in file paths on Windows systems in PHP?

Using backslashes (\) instead of forward slashes (/) in file paths on Windows systems can cause issues with file paths not being recognized correctly by PHP functions. To avoid this problem, it is recommended to always use forward slashes (/) in file paths when working with PHP on Windows systems.

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

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