MySQLi查询失败,没有错误代码

Question

我一直在一个名为FreeHostia的免费托管网站上进行一些网络开发测试.我一直在尝试通过PHP创建数据库.然而,我的努力是徒劳的.查询失败,我没有错误代码.我的PHP代码如下所示:

<?php 
    // Create connection
    $con=mysql_connect("localhost", "raslar10_players", "123456", "raslar10_players");

    if (mysqli_connect_errno()) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    } else {
        echo "Connected to MySQL";
    }

    // Create table
    $sql = "CREATE TABLE Persons(FirstName CHAR(30),LastName CHAR(30),Age INT)";

    if (mysqli_query($con, $sql)) {
        echo "Table persons created successfully";
    } else {
        echo "Error creating table: " . mysqli_error($con);
    }

    ?>

我做错了什么？该查询在phpMyAdmin中工作,并且连接正在运行.(根据我的代码,反正)

Answer 1

只是改变

$con=mysql_connect("localhost", "raslar10_players", "123456", "raslar10_players");

至

$con=mysqli_connect("localhost", "raslar10_players", "123456", "raslar10_players");
