php桌面无法与MYSQL工作台连接
我使用 MYSQL 工作台作为数据库和 PHP 连接到 MYSQL 工作台，同时连接我收到以下错误。
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>
以上是我用来将数据插入 MySQL 工作台数据库但不断收到上述错误的代码。
