关闭自动提交，做一些查询，然后提交查询：

<?PHP
 $con=mysqli_connect("localhost","my_user","my_password","my_db");
 // Check connection
 if (mysqli_connect_errno($con))
 {
 echo "Failed to connect to MySQL: " . mysqli_connect_error();
 }

// Set autocommit to off
mysqli_autocommit($con,FALSE);

// Insert some values 
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age)
 VALUES ('Peter','Griffin',35)");
 mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age) 
 VALUES ('Glenn','Quagmire',33)");

// Commit transaction
mysqli_commit($con);

// Close connection
 mysqli_close($con);
?>
