2. Reset session_save_path. After the setting is completed, restart iis to see if it is successful. If not, please set two, because there are two in php.ini for compatibility with previous versions. One is commented out, one is above 4.0 and one is above 5.0. After the setting is completed, set the set directory to read and write by everyone, and then inherit it. Do not check other boxes. This ensures the security of the saved directory and the security of system data.
