Summary of online game exercises (1), _PHP tutorial

网游练习总结(1)，

最近一段时间在校也闲得没事干，反正是好长一段时间，干脆就做一个《中国象棋》网游耍耍打发时间。弄了好久没有写总结，以及整个过程中遇到的问题，今天就赶紧写一哈，难免后面就会忘了。

一、注册登录界面：

    可能会说这么简单的游戏，网上可能例子很多，也没有必要弄注册这样的功能，其实我只是学着玩玩哈。

关于注册我使用的是php与as3.0交互做的，有与php学的非常浅，也遇到了不少问题：

1.检测是否注册成功：这个也困了时间不是很长，但是觉得比较重要，我搜了一些资料找到的：

mysql_affected_rows()// 函数返回前一次 MySQL 操作所影响的记录行数。执行成功，则返回受影响的行的数目，如果最近一次查询失败的话，函数返回 -1。

2.邮箱激活验证：

这个需要配置SMTP服务，现在QQ邮箱网易邮箱等都可以去设置，然后作为代理邮箱。

$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);<br />$smtp->debug = false;//关闭调试<br />$state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);<br />

在整个数据库操作过程中使用一个变量来监控是否出现操作错误，来返回是否注册成功；

error_reporting(E_ERROR | E_WARNING | E_PARSE);//屏蔽所有错误警告等

Resource id #num

由于本人是一枚初学者，对mysql查询返回值等理解不够，遇到了一点困惑，mysql_query() 仅对 SELECT，SHOW，EXPLAIN 或 DESCRIBE 语句返回一个资源标识符，如果查询执行不正确则返回 FALSE。要使用mysql_fatch_array()函数或者mysql_fetch_object()函数进行转换，然后对相应数组或者对象进行操作。

总的来说这部分遇到的困难也不是很多，经过自己的努力很快就解决了。
