XAMPP 7.3.5 + SQL Server + CodeIgniter 3.1 配置

1.下载 XAMPP 7.3.5 https://www.apachefriends.org/index.html

2.下载 Microsoft Drivers 5.6 for PHP for SQL Server https://www.microsoft.com/en-us/download/details.aspx?id=57916

3.下载 Microsoft ODBC Driver 17 for SQL Server https://www.microsoft.com/zh-CN/download/details.aspx?id=56567

所需软件如上，php.ini增加：

extension=php_sqlsrv_73_ts_x64.dll

启动apache后，在htdocs里编个文件sqlserver-test.php测试：

'sa','PWD' =>'pass','Database' =>'MyDB');
$conn = sqlsrv_connect($serverName,$connectionInfo);
if($conn){
    echo "ok";
}else{
    echo "err.";
    die(print_r(sqlsrv_errors(),true));
}
?>

4.配置CI
1）database.php配置：
 

*/
$active_group = 'default';//'default';
$query_builder = TRUE;

$db['default'] = array(
    'dsn'    => '',
    'hostname' => 'IP',
    'port'     => 'PORT',
    'username' => 'sa',
    'password' => 'pass',
    'database' => 'MyDB',
    'dbdriver' => 'sqlsrv',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

2）在控制器Welcome.php增加一个函数代码，做一下测试：

    function mssqltest(){
        $this->load->database();
        $query = $this->db->query("select * from products");
        foreach ($query->result() as $row)
        {
            echo $row->pr_id;
            echo $row->pr_name;
            echo $row->pr_date;
        }

        echo 'Total Results: ' . $query->num_rows();
    }

3）在浏览器浏览测试：
