What are the potential issues when switching from a Windows-based PHP editor to a Linux-based one?

One potential issue when switching from a Windows-based PHP editor to a Linux-based one is that the file paths may be different due to the operating system variations. To solve this issue, you can use the PHP predefined constant `DIRECTORY_SEPARATOR` to ensure cross-platform compatibility in defining file paths.

// Define file path using DIRECTORY_SEPARATOR constant
$filePath = 'path' . DIRECTORY_SEPARATOR . 'to' . DIRECTORY_SEPARATOR . 'file.php';
