html form part
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>表单联合PHP进行交互</title>
</head>
<body>
<form action="http://localhost/MyService/service.php" method="get">
<!--action属性代表的是想要运行的网页的地址，methon属性代表方式-->
<p>用户名：<input type="text" name="name"></p>
<p>密码：<input type="password" name="passworld"></p>
<input type="submit" value="确定">
</form>
</body>
</html>PHP part
<?php echo "用户名：".$_GET['name']."<br>密码：".$_GET['passworld']; //.$_GET前面的.表示的是连结，文字部分用"".这里是HTML所创建的GET的创建方式，要对应 //如果用post方式提交的话，这里就随之改变，post方式直接将用户名和密码添加到地址栏中而post不用，较安全
