我在弄清楚如何使这段代码工作时遇到了问题。我想将HTML表单中的数据插入到我设置的本地MySQL数据库中。
HTML：
<!DOCTYPE html>

<title>Database Project</title>
<link rel="stylesheet" type="text/css" href="stylesheet.css"/>

<body>
<div id="Container">

<div id="Body">
<h3>Register a movie database:</h3>
<p>Are you a new director who just made a stunning movie? Or are you an actor with several movies on your resume. No matter what you are people need a way to find your movies. Well now you can! Upload your movie, director and or actor information down below:</p>

mysql_query($query);
echo '<script language="Javascript">alert("User was successfully created.");</script>';
mysqli_close($connection);

?>
问题是，只要我填写表单并提交，我就会在浏览器中获取PHP代码。没有执行，只有代码。如果有人能发现问题，那将非常感激！
