php中form表单同时使用POST和GET传递参数说明

<?php
 print_r($_GET);
 print_r($_POST);
?>
 
<form action="get_post.php?id=100" method="post">
姓名:<input type="text" name="name" /><br>
年龄:<input type="text" name="age" /><br>
<input type="submit" value="提交" />
</form>

<?php
 /**
  *测试get和post提交
  *@link(http://www.111cn.net)
  */
 print_r($_GET);
 print_r($_POST);
?>
 
<form action="get_post.php?id=100" method="get">
姓名:<input type="text" name="name" /><br>
年龄:<input type="text" name="age" /><br>
<input type="submit" value="提交" />
</form>
