所以我从w3schools那里学到了这个......但是这个例子使用了直接注入到代码中的数据。我想知道如何使用相同的代码块，但是从表单中接收数据

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDBPDO";

try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username,      
$password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// prepare sql and bind parameters
$stmt = $conn->prepare("INSERT INTO MyGuests (firstname, lastname, 
email) 
VALUES (:firstname, :lastname, :email)");
$stmt->bindParam(':firstname', $firstname);
$stmt->bindParam(':lastname', $lastname);
$stmt->bindParam(':email', $email);

// insert a row
$firstname = "John";
$lastname = "Doe";
$email = "john@example.com";
$stmt->execute();

// insert another row
$firstname = "Mary";
$lastname = "Moe";
$email = "mary@example.com";
$stmt->execute();

// insert another row
$firstname = "Julie";
$lastname = "Dooley";
$email = "julie@example.com";
$stmt->execute();

echo "New records created successfully";
}
catch(PDOException $e)
{
echo "Error: " . $e->getMessage();
}
$conn = null;
?>

我觉得你应该先学会PHP Form Handling
示例make form.html为

<html>
<body>

<form action="insert.php" method="post">
Name: <input type="text" name="firstname"><br>
Name: <input type="text" name="lastname"><br>
E-mail: <input type="text" name="email"><br>
<input type="submit">
</form>

</body>
</html>

然后对数据库进行数据处理make insert.php

<?php
$servername = "localhost";
$username = "root";
$password = "yaskur";
$dbname = "test";

$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// prepare sql and bind parameters
$stmt = $conn->prepare("INSERT INTO MyGuests (firstname, lastname, email) 
                        VALUES (:firstname, :lastname, :email)");
$stmt->bindParam(':firstname', $firstname);
$stmt->bindParam(':lastname', $lastname);
$stmt->bindParam(':email', $email);

// insert a row
$firstname = $_POST["firstname"];
$lastname = $_POST["lastname"];
$email = $_POST["email"];
$stmt->execute();
