一:环境搭建
sqlserver2005或者sqlserver2008
请先到此处下载驱动
http://www.microsoft.com/downloads/details.aspx?FamilyId=61BF87E0-D031-466B-B09A-6597C21A2E2A&displaylang=en
下载后解压文件
配置:
1.将解压的php_sqlsrv.dll 和 php_sqlsrv_ts.dll 放到PHP的扩展目录中(PHP\EXT)。
2.编辑php.ini文件(在windows文件夹下),添加以下扩展:
extension=php_sqlsrv.dll
extension=php_sqlsrv_ts.dll
3.去掉;extension=php_mssql.dll前的分号
注意=号右边是解开过后的扩展的两个驱动的文件名,必须保证此文件在配置好的扩展目录内,而且需要注意此处最初不需要带";"。";"在php.ini文件里面,首部分号的含义代表行注释,如果有分号的时候,服务器在读取配置的时候会略过分号这一行不去读取相关内容,只有没有加分号的行才会被服务器读取。
这里解释一下,两个驱动程序的区别在于,php_sqlsrv_ts.dll是线程安全的驱动,如果服务器本身的环境是使用的php5ts.dll,就是用这个驱动;php_sqlsrv.dll不是线程 安全的,这种情况下,服务器运行PHP应该加载的是php5.dll
4测试配置环境:
整个过程操作好了过后,写一个test.php测试一下配置的相关环境,测试代码如下:
phpinfo();
?>
若出现以下图片证明环境已经配置好了:
二:连接测试
SQL Server常用的有两种认证方式,一种是本地系统账户认证(Windows Authentication ),一种是使用用户名和密码(SQL Server Authentication ),第二种认证方式必须启用SQL Server的混合模式。
1.Windows Authentication连接部分代码段:
$serverName = "(local)";
$connectionInfo = array("Database"=>"TestingInfo","ConnectionPooling"=>false);
$conn = sqlsrv_connect( $serverName,$connectionInfo);
if(! $conn){
echo "o no!!!!!";
die( print_r( sqlsrv_errors(), true));
}else{
echo "yes done";
}
?>
2.SQL Server Authentication连接部分代码段:
$serverName = "(local)";
$uid = "dbusername";//数据库用户名
$pwd = "dbuserpass";//数据库用户密码
//下面的Database为数据库名
$connectionInfo = array("UID"=>$uid,"PWD"=>$pwd,"Database"=>"dbname");
$conn = sqlsrv_connect( $serverName,$connectionInfo);
if(! $conn){
echo "o no!!!!!!!";
die( print_r( sqlsrv_errors(), true));
}else{
echo "yes done";
}
?>

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
