【问题描述】：

我在使用 codeigniter 与数据库建立连接时遇到问题。我已经尝试了很多并测试了不同人给出的许多解决方案，但到目前为止还没有成功。

我在codeigniter中的配置是：

$db['default']['hostname'] = 'DX-PC\MSSQLSERVER';
//$db['default']['port'] = 1433;
$db['default']['username'] = 'myusername';
$db['default']['password'] = 'mypass';
$db['default']['database'] = 'mydbname';
$db['default']['dbdriver'] = 'sqlsrv';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE; //default: TRUE
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

所以，它给了我以下错误：

发生数据库错误无法使用提供的设置连接到您的数据库服务器。

同样，我已经尝试使用以下代码在不使用 codeigniter 的情况下与 MS SQL 服务器建立连接：

    echo 'called';

    echo "<br>";

    $serverName = "DX-PC\\MSSQLSERVER"; //serverName\instanceName
    $connectionInfo = array( "Database"=>"mydbname", "UID"=>"myusername", "PWD"=>"mypass");
    $conn = sqlsrv_connect( $serverName,$connectionInfo);
    if( $conn ) {
        echo "Connection established.<br />";
    }else{
        echo "Connection could not be established.<br />";
        echo "<pre>";
        print_r(sqlsrv_errors());
        echo "</pre>";
    }

它给了我这些错误：

called Connection could not be established.

我已经尝试了来自不同论坛和 stackoverflow 的所有解决方案，但没有成功。请帮助我。谢谢

【问题讨论】：

在 .htaccess 文件中，检查或更正您的网址：RewriteRule ^(.*)$ /yourRootFolder/index.php?/$1 [L]
RewriteEngine On RewriteBase /cheddargetter/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /cheddargetter/index.php? /$1 [L] 我已经改变了它。仍然出现 db 错误

标签： php sql-server database codeigniter sqlsrv

【解决方案1】：

过去我也有问题，所以我用了经典的方法：

$server = "x.x.x.x\MSSQL2005,1435";
$user = "xxxx";
$pass = "xxxx";

$this->ms  = mssql_connect($server, $user, $pass) or die ("No connection");

【解决方案2】：

是的，我已经想通了，它现在正在工作。以下更改使其正常工作。

之前的配置，您必须在之前完成。即（扩展名：sqlsrv_*.dll 等添加到 php.ini 等）
将 .htaccess 中的重写规则从 RewriteRule ^(.)$ /index.php?/$1 [L] 更改为 RewriteRule ^(.)$ /yourrootfolder/index.php ?/$1 [L]（由 SHAZ 提供）
其次，因为我有一个名为 MSSQLSERVER 的默认实例，所以它不需要写 $db['default']['hostname'] = 'DX-PC\MSSQLSERVER';而是写了 $db['default']['hostname'] = 'DX-PC';

我希望这可以帮助其他人。谢谢。
