Case 3: Use post and get methods to pass parameters between php and html

case3.php:

<!DOCTYPE html>
<html>
<head>
    <!-- 请将文档保存为UTF-8编码，否则中文会乱码 -->
    <meta charset="UTF-8">
    <title>案例3</title><!-- 使用post和get方法在php和html间传递参数 -->
</head>

<body>

<!-- 使用get方法传递 -->
<form action="case3-output.php" method="get">
    get提交的数据：<input type="text" name="getText">
    <input type="hidden" name="getHidText" value="get隐藏文字">
    <input type="submit" name="g_sb"><!--提交按钮，只有提交了才能够传递表单参数-->
</form>

<!-- 通过url直接传递，也属于get方法 -->
<a href="case3-output.php?urlText=传递文字">点击超链接传递参数</a>

<!-- 使用post方法传递 -->
<form action="case3-output.php" method="post">
    post提交的数据：<input type="text" name="postText" >
    <input type="hidden" name="postHidText" value="post隐藏文字">
    <input type="submit" name="p_sb"><!--提交按钮，只有提交了才能够传递表单参数-->
</form>

</body>

</html>
