How to deal with case errors in PHP file paths and generate corresponding error messages. In the process of developing PHP programs, we often encounter the problem of case errors in file paths. Since Windows and Linux systems handle file path case differently, when the program passes the test using the Windows system in the development environment, it may cause path errors when it is deployed to the Linux server. In order to solve this problem, we can use some methods to deal with the large file path
