When transferring the entire file to the server, a 500 error was encountered.

Process: All thinkphp files are generated on your own computer, and then the entire file is transferred to the server.

Analysis: Then the problem comes. When uploading, the runtime file is also uploaded. The Runtime directory is the working directory of thinkphp and must have write permission. If there is no such directory, thinkphp will create it by itself. When the Runtime directory is placed on the server, it becomes read-only, so an error is reported.

Solution: Delete the Runtime on the server and revisit the index.php (referencing the thingPHP framework) file, the Runtime will be automatically generated.
