升级php后phpmyadmin无法登陆

php php.ini phpmyadmin generally Down upgrade back Condition yes Login Configuration question

 

一般情况是PHP.ini配置问题,根据下面的配置项再设置一次,然后重启服务器,试试!

 

(1) 设置扩展路径

 

  查找extension_dir 有这么一行

 

  ;extension_dir = "./"

 

  在此行后面加入一行(注意是加入一行,不是加到后面)

 

  extension_dir = "d:\php\ext"

 

  其中d:\php是你安装php的路径。路径不正确将无法加载dll

 

  (2) 查找extension

 

  extension=php_mbstring.dll

 

  extension=php_gd2.dll

 

  extension=php_mysql.dl

 

  把上面3项前面的分号去掉,这样IIS启动时就可以加载这些dll了

 

  (3) 设置会话保存路径

 

  查找session.save_path 有这么一行

 

  ; session.save_path = "N;/path"

 

  在此行后加入一行

 

  session.save_path = "C:\Windows\Temp"

 

  保存到你的临时目录下,这里完全可以保存到Windows临时目录Temp下

 

  (4) 还有比较值得注意的是short_open_tag 默认是Off的

 

  也就是说php不能使用短标记如 ?> 必须使用

 

  由于短标记使用方便,并且很多程序也是用短短标记来写,如discuz等

 

  如果不把short_open_tag 改成On将出现的症状将很难判断是上面原因,这里建议修改

 

  查找

 

  short_open_tag = Off

 

  改为

 

  short_open_tag = On

 

  (5) 是否显示错误display_errors

 

  出于安全性考虑,display_errors 也默认为Off

 

  就是说在调试时,如果php代码有误,就只出现一个空白页。而不会显示出错原因和出错行数。

 

  这样调试起来将非常不便,建议根据自己需要修改

 

  查找

 

  reGISter_globals = Off

 

  改成

 

  register_globals = On

 

  (6) register_globals

 

  出于安全性考虑它默认也是Off

 

  当register_globals=Off的时候,下一个程序接收的时候应该用$_POST['user_name']和$_POST['user_pass'])

 

  当register_globals=On的时候,下一个程序可以直接使用$user_name和$user_pass来接受值。
