HomeBackend DevelopmentPHP Tutorialphp连接sql server的三种方法小结

参考php手册,对php连接sql server系列做出个小结。主要有三种方式:

一、通过mssql_系列函数,主要针对php5.3以下的版本和sqlserver2000及以上版本使用。在php.ini中将;extension=php_mssql.dll;extension=php_msql.dll;extension=php_pdo_mssql.dll ;extension=php_pdo_odbc.dll 前面的分号去掉。

二、通过sqlsrv_系列函数,主要针对php5.3以上的版本和sql server 2005以上版本使用。需要下载安装Microsoft Drivers for PHP for SQL Server驱动,地址:https://msdn.microsoft.com/library/dn865013.aspx。下载后解压放到php对应的ext目录下。然后打开php.ini文件,在extension 后面添加一下配置

extension=php_pdo_sqlsrv_53_ts.dll
extension=php_sqlsrv_53_ts.dll

重启apache,查看phpinfo(),确保apache已经支持sqlsrv。如下图所示:

 

 

 

 

并且安装sqlncli.msi,这个文件是协助windows环境访问sql server所在的数据库服务器的

三、通过odbc方式连接sqlserver系列。需要在php.ini中开启odbc系列扩展。在phpinfo函数中看到

下面是实现代码:


// $serverName = "localhost";
// $connectionInfo = array( "Database"=>"JXC_ERP", "UID"=>"sa", "PWD"=>"123456");
// $conn = sqlsrv_connect( $serverName, $connectionInfo );
// if( $conn === false ) {
    // die( print_r( sqlsrv_errors(), true));
// }

// $sql = "SELECT * FROM dbo.A_PHP";
// $stmt = sqlsrv_query( $conn, $sql );
// if( $stmt === false) {
    // die( print_r( sqlsrv_errors(), true) );
// }


// while($row = sqlsrv_fetch_array($stmt))
// {echo $row[0]."-----".$row[1]."
";}

$con = odbc_connect('JXC_ERP','sa','123456');
$query = "SELECT * FROM dbo.A_PHP";
$result = odbc_do($con,$query);
while(odbc_fetch_row($result))
{
    $list = odbc_result($result, "id"); print_r($list);echo '
';
}


// $server ="localhost";  //服务器IP地址,如果是本地,可以写成localhost
// $uid ="sa";  //用户名
// $pwd ="123456"; //密码
// $database ="JXC_ERP";  //数据库名称
 
////进行数据库连接
// $conn =mssql_connect($server,$uid,$pwd) or die ("connect failed");
// mssql_select_db($database,$conn);
 
////执行查询语句
// $query ="select * from A_PHP";
// $row =mssql_query($query);
 
////打印输出查询结果
// while($list=mssql_fetch_array($row))
// {
       // print_r($list);
       // echo "
";
// }

?>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
