我全局查找到三个session.save_path地址我都修改了/usr/local/php/var 重启了php但是还是不行呢

Argument passed to save_handler.  In the case of files, this is the path

; where data files are stored. Note: Windows users have to change this

; variable in order to use PHP's session functions.

;

; The path can be defined as:

;

;     session.save_path = "/usr/local/php/var"

;

; where N is an integer.  Instead of storing all the session files in

; /path, what this will do is use subdirectories N-levels deep, and

; store the session data in those directories.  This is useful if you

; or your OS have problems with lots of files in one directory, and is

; a more efficient layout for servers that handle lots of sessions.

;

; NOTE 1: PHP will not create this directory structure automatically.

;         You can use the script in the ext/session dir for that purpose.

; NOTE 2: See the section on garbage collection below if you choose to

;         use subdirectories for session storage

;

; The file storage module creates files using mode 600 by default.

; You can change that by using

;

;     session.save_path = "/usr/local/php/var"

;

; where MODE is the octal representation of the mode. Note that this

; does not overwrite the process's umask.

; Whether to use cookies.

session.use_cookies = 1
