Answer 1

你所拥有的mysqli发送与查询的连接。像这样：

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

// Perform queries 
mysqli_query($con,"SELECT * FROM Persons"); 
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age) 
VALUES ('Glenn','Quagmire',33)"); 

mysqli_close($con); 
?>
