Online Games Exercise Summary (1),

The recent period of time in school also free to do nothing, anyway is a good long time, simply do a "Chinese chess" online games to kill time to play. After a long time did not write summary, and the whole process encountered problems, today hurriedly write a ha, inevitably behind will forget.

First, registration Login interface:

May say such a simple game, there may be many examples on the Internet, there is no need to register such a function, in fact, I just learn to play ha.

About registration I use PHP and as3.0 Interactive, there is very shallow with PHP, but also encountered a lot of problems:

1. Check whether the registration is successful: This also sleepy time is not very long, but feel more important, I searched some information to find:

The mysql_affected_rows ()//function returns the number of record rows affected by the previous MySQL operation. If the execution succeeds, the number of rows affected is returned, and if the last query fails, the function returns-1.

2. Mailbox Activation Verification:

This need to configure the SMTP service, now QQ mailbox NetEase mailbox can go to set up, and then as a proxy mailbox.

$SMTP = new SMTP ($smtpserver, $smtpserverport, True, $smtpuser, $smtppass);
$SMTP->debug = false;//off debugging
$state = $smtp->sendmail ($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);

A variable is used during the entire database operation to monitor whether an operation error occurred and to return the registration success;

Error_reporting (E_error | e_warning | E_parse);//Block all error warnings, etc.

Resource ID #num

Because I am a beginner, the MySQL query return value and other understanding is not enough, encountered a little confusion, mysql_query () only the Select,show,explain or DESCRIBE statement returns a resource identifier, if the query is executed incorrectly returns FALSE. To convert using the Mysql_fatch_array () function or the mysql_fetch_object () function, then manipulate the corresponding array or object.

In general, this part of the difficulties encountered is not many, after their own efforts are quickly resolved.
