随机抽取10个幸运户与密码
各位前辈大家好，我是刚刚准备入门的小弟，先问声好。
我学了php的变量，先要做一道题，但是没有思路，不知道该怎么写，希望大家帮忙一下，谢谢。
题目是：在在莫大型论坛中随机抽取10个新幸运用户账号以及对应的密码。账号有数字或者英文字母组成，长度在6-8之间且首字母必须是英文字母，密码的长度只能是6.创建10位新用户，并存入数组$user中，同时打印用户的信息。
这道题有提示：1.使用随机函数rand();
2.将账户信息存放于二维数组$userName,定义数组格式为：$userName=array();
3.合并一个或多个数组时使用array_merge(),用法为：array_merge($arrayt1,$array2);
4.使用print_r()或者foreach打印数组。
虽然给了提示，但是凭我所学变量的一点皮毛，是在不知道该怎么下手。帮帮忙，谢谢啦。
