5, Incompatibility issues that are easy to encounter in the PHP environment

(1) The data directory does not have write permission, resulting in the system session being unusable, which will result in the inability to log in to the management background (directly manifested as the verification code cannot be displayed normally);

(2) The temporary folder uploaded by php is not set properly or does not have write permission, which will cause the file upload function to be unusable;

(3) Inexplicable errors occur, such as When installing, a blank display may be caused by the system not loading the mysql extension. For beginners, you can download dede's php package for easy and simple use.
