Warning: Unknown(): open(/tmp\sess_84cb589ea249708b09c3d5e6836fdd0d, O_RDWR) failed: No such file or directory (2) in Unknown on line 0
Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
就是 session变量需要系统的临时空间,session.save_path = "设置一个有效文件夹的绝对路径" ,(比如 session.save_path = "C:\WINDOWS\temp" )
session.save_path =前面的 ' ; '号去掉 ,另外编辑该文件夹的权限 添加EVERYONE 有写入修改权限即可 !
