php使用session提示[function.session-start]: open解决方法
在使用php做后台管理时会碰到用户登录页面会提示Warning: session_start() [function.session-start]: open...错误了,后面跟着是failed: No such file or directory了,这个是告诉我们目录不存了了,下面我来给各位介绍问题解决方案
如我们我的测试111.php文件如下一段代码
session_start();
$_SESSION['admin'] =$_POST['username'];
?>
运行代码提示
Warning: session_start() [function.session-start]: open(/tmpsess_84cb589ea249708b09c3d5e6836fdd0d, O_RDWR) failed: No such file or directory (2) in E:webhtdocswww.111cn.net111.php on line 9
从上面错误提示是有一句failed: No such file or directory提示了,是告诉我人找不到session缓存要写的目录了,这样我就知道原因所在了
解决办法
SESSION文件保存目录不存在。建一个就行了。
查看PHP.INI中
session.save_path = /tmp
改成你要保存的路径如session.save_path = "E:/server/php5/session_temp"
重启服务器即可。
