Question

我正在使用MYSQL工作台作为数据库，并在连接时使用PHP连接到MYSQL工作台，但出现以下错误。

Warning: mysqli::__construct(): Server sent charset (255) unknown to the client. Please, report to the developers in C:\Users\phpdesktop\phpdesktop-chrome-57.0-rc-php-7.1.3\www\index.php on line 3

和

Warning: mysqli::__construct(): (HY000/2054): Server sent charset unknown to the client. Please, report to the developers in C:\Users\phpdesktop\phpdesktop-chrome-57.0-rc-php-7.1.3\www\index.php on line 3

和

Warning: mysqli::query(): Couldn't fetch mysqli in C:\Users\phpdesktop\phpdesktop-chrome-57.0-rc-php-7.1.3\www\index.php on line 13

以下是我的代码

<?php $conn = new mysqli('localhost' , 'root' , '' , 'database_name'); 

if(isset($_POST['submit'])) {

// insert username into the database table

$Username = $conn->real_escape_string(stripslashes(trim($_POST['Username'])));

$conn->query("INSERT INTO table_name (Username) VALUES ('$Username'");

}

?>

<!DOCTYPE>

<html>

<head>

<meta = charset=UTF-8>
<title>Insert Username</title>
</head>
<body>
<form name="username" method="post" action="">
<p>Username<br>

<input type="text" name="Username">
</p>
<p>
<input type="submit" name="submit" value="Submit">
</p>
</form>
</body>

</html>

上面是我用来将数据插入MySQL工作台数据库但不断出现上述错误的代码。

您必须将以下代码添加到/etc/mysql/conf.d并重新启动mysqld：

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8


[mysqld]
collation-server = utf8_unicode_ci
character-set-server = utf8

php桌面无法与MYSQL工作台连接
