如何使用一个php页面处理多个php表单

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST["form1"])) {
        // 处理表单1的代码
        $name = $_POST["name1"];
        $email = $_POST["email1"];
        // 其他处理逻辑...

        // 示例：将数据存储到数据库
        // $sql = "INSERT INTO table1 (name, email) VALUES ('$name', '$email')";
        // 执行数据库插入操作...

        echo "表单1提交成功！";
    } elseif (isset($_POST["form2"])) {
        // 处理表单2的代码
        $username = $_POST["username2"];
        $password = $_POST["password2"];
        // 其他处理逻辑...

        // 示例：将数据存储到数据库
        // $sql = "INSERT INTO table2 (username, password) VALUES ('$username', '$password')";
        // 执行数据库插入操作...

        echo "表单2提交成功！";
    }
}
?>

<form action="" method="post">
    <!-- 表单1 -->
    <input type="text" name="name1" placeholder="姓名">
    <input type="email" name="email1" placeholder="邮箱">
    <input type="submit" name="form1" value="提交表单1">
</form>

<form action="" method="post">
    <!-- 表单2 -->
    <input type="text" name="username2" placeholder="用户名">
    <input type="password" name="password2" placeholder="密码">
    <input type="submit" name="form2" value="提交表单2">
</form>
