<?php
header("content-type:text/html;charset=utf-8");
//作用:登录处理（验证登录是否成功）
//获得表单提交的用户名、密码
$userName = $_POST["userName"];
$password = $_POST["password"];
//获得user.txt中的用户列表信息
$user = "";
$handle = fopen("user.txt","r");
while($str=fgets($handle))
{
$user .= $str;
}
fclose($handle);
$userList = unserialize($user);//二维数组
?>
<?php
header("content-type:text/html;charset=utf-8");
//作用:将$userList二维数组写入user.txt文件中
$userList = array(
array("userName"=>"hello","password"=>"123456"),
array("userName"=>"张三","password"=>"123456"),
array("userName"=>"tom","password"=>"123456"),
array("userName"=>"田七","password"=>"123456")
);
$handle = fopen("user.txt","w");
fputs($handle,serialize($userList));
fclose($handle);
?>
