This article mainly introduces the interaction between PHP and Web pages. It has a certain reference value. Now I share it with everyone. Friends in need can refer to it

1.form form default situation The way to submit data is the get method.

2. The predefined variables used by PHP scripts to process form data are $_GET, $_POST (case sensitive)

Code example (Pay special attention to adding the array when adding the checkbox attribute name)

##simpleTest.html

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Insert title here</title></head><body><form action="simpleForm.php" method="post">
    用户名:<input type="text" name="username"><br>
    密码：<input type="text" name="password"><br>
    <!-- 复选框 -->
     学过的编程语言是：<br>
    <input type="checkbox" name="language[]" value="PHP">php    
    <input type="checkbox" name="language[]" value="java">java    
    <input type="checkbox" name="language[]" value="C#">C#
