    }



    //$this->load->view('home/index', $data);
    //$this->output->enable_profiler(TRUE);
}

the line is $data['memcache'] = new Memcache;

这行是$ data ['memcache'] =新的Memcache;

2 个解决方案

#1

Maybe the .htaccess is not in the correct directory.. you may want to check it, should be inside your project directory. if so,

也许.htaccess不在正确的目录中..您可能想要检查它,应该在您的项目目录中。如果是这样,

put this in your .htaccess file

把它放在.htaccess文件中

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

#2

You might want to also check your httpd.conf file and see if apache is allowed to "honor" your .htaccess file. Search for the AllowOverride command and change it from AllowOverride None (the default) to AllowOverride All.

您可能还想检查httpd.conf文件,看看是否允许apache“兑现”.htaccess文件。搜索AllowOverride命令并将其从AllowOverride None(默认值)更改为AllowOverride All。

ALSO: Do not forget to restart the httpd server afterwards.

另外:不要忘记之后重启httpd服务器。
