一、php和表单

1.POST方法手动发送数据:

二者部分区别:

GET:

1.将信息聚集起来作为URL一部分传送

2.传送数量有限

3.公开传送,诸如密码信息会暴露

4.创建的表单可以添加为书签。

POST:

1.传递的信息用户看不到


用法示例:

html文件:ws.html

   <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base>  <div id="awindow">
<form action="handle.php" method="post"> <p> Name:<select name="title"> <option value="Mr">Mr</option> </select> <input type="text" name="name" size="20"></p> <input type="submit" value="send">
</form>    <br> php文件:handle.php  <br>  <p></p>  <p></p>  <pre name="code" class="sycode">   <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base>   <div id="awindow">
<?phpini_set ('display_errors', 1);error_reporting(E_ALL|E_STRICT);<strong><span style="color:#ff0000;">$title=$_POST['title'];$name =$_POST['name'];</span>print "<p> hello <span style="color:#ff0000;">$title $name</span>";?>  输入:myname  </p>
