关于Php连接MSSQL,我们可以使用PDO、ODBC和SQL Server三种方式,下面分别详细介绍。
1. 使用PDO连接MSSQL
安装PDO和pdo_sqlsrv驱动
使用PDO连接MSSQL需要安装PDO和pdo_sqlsrv驱动,可以通过以下命令安装:
sudo apt-get install php7.0-pdo
sudo apt-get install php7.0-sqlsrv
连接MSSQL服务器
try {
$server_name = "localhost";
$database_name = "test_db";
$username = "sa";
$password = "sa123456";
$pdo = new PDO("sqlsrv:Server=$server_name;Database=$database_name", $username, $password);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully!\n";
} catch (PDOException $e) {
echo "Failed to connect to MSSQL: " . $e->getMessage();
}
2. 使用ODBC连接MSSQL
安装odbc和odbc驱动
使用ODBC连接MSSQL需要安装odbc和odbc驱动,可以通过以下命令安装:
sudo apt-get install unixodbc-dev
sudo pecl install pdo_odbc
连接MSSQL服务器
try {
$server_name = "localhost";
$database_name = "test_db";
$username = "sa";
$password = "sa123456";
$dsn = "odbc:Driver={SQL Server};Server=$server_name;Database=$database_name";
$pdo = new PDO($dsn, $username, $password);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully!\n";
} catch (PDOException $e) {
echo "Failed to connect to MSSQL: " . $e->getMessage();
}
3. 使用SQL Server连接MSSQL
安装sqlsrv
使用SQL Server连接MSSQL需要安装sqlsrv,可以通过以下命令安装:
sudo apt-get install php7.0-sqlsrv
连接MSSQL服务器
try {
$server_name = "localhost";
$database_name = "test_db";
$username = "sa";
$password = "sa123456";
$connection_info = array( "Database"=>$database_name, "UID"=>$username, "PWD"=>$password);
$conn = sqlsrv_connect( $server_name, $connection_info );
if( $conn ) {
echo "Connected successfully!\n";
} else {
echo "Failed to connect to MSSQL\n";
die( print_r( sqlsrv_errors(), true));
}
} catch (PDOException $e) {
echo "Failed to connect to MSSQL: " . $e->getMessage();
}
以上就是连接MSSQL的三种方式,分别使用PDO、ODBC和SQL Server。根据不同的需求选择不同的方式来连接MSSQL。
