本文实例讲述了php使用sql server验证连接数据库的方法。分享给大家供大家参考。具体分析如下:

当您连接到 SQL Server 时,SQL Server Driver for PHP 支持 SQL Server 身份验证,在使用 SQL Server 身份验证连接到 SQL Server 时必须考虑以下几点.

必须对服务器启用 SQL Server 混合模式身份验证,在尝试建立连接时必须设置 UID 和 PWD 连接属性,UID 和 PWD 必须映射到有效的 SQL Server 用户和密码.

注意:包含右大括号 (}) 的密码必须使用另一个右大括号进行转义,例如,如果 SQL Server 密码为“pass}word”,则 PWD 连接属性的值必须设置为“pass}}word”.

在使用 SQL Server 身份验证连接到 SQL Server 时应采取以下预防措施,下面看一个简单的实例,代码如下:

代码如下:

$serverName = "(local)";
$uid = 'xxxx';
$pwd = 'xxxx';
$connectionInfo = array( "UID"=>$uid,
                         "PWD"=>$pwd,
                         "Database"=>"AdventureWorks");
 
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false )
{
     echo "无法连接数据库.";
     die( print_r( sqlsrv_errors(), true));
}
 
$tsql = "SELECT CONVERT(varchar(32), SUSER_SNAME())";
$stmt = sqlsrv_query( $conn, $tsql);
if( $stmt === false )
{
     echo "查询错误.";
     die( print_r( sqlsrv_errors(), true));
}
 
$row = sqlsrv_fetch_array($stmt);
echo "登录的用户: ".$row[0];
 
sqlsrv_free_stmt( $stmt);
sqlsrv_close( $conn);
?>
