<?php
$ip=$REMOTE_ADDR;
echo $ip;
?>
打开页面的时候是空的但是把ip赋值成一个数就可以在页面上显示<?php
$ip=abc
echo $ip;
?>
这是怎么回事?
还有个问题,就是php.ini文件中,怎么有好多个 session.save_path?

echo $ip;第二个问题,相关配置发上来看看。
; Handler used to store/retrieve data.
session.save_handler = files; 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.
;
; As of PHP 4.0.1, you can define the path as:
;
session.save_path = "C:/tmp";
; 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 = "N;MODE;/path";
; where MODE is the octal representation of the mode. Note that this
; does not overwrite the process's umask.
session.save_path = "C:/tmp"
; Whether to use cookies.
session.use_cookies = 1怎么这么多个session.save_path?
有分号(;)屏蔽了配置参数应该没事吧?
session.save_path = "C:/tmp; 两个是重复参数耶!!!
