PHP beginners write small programs that promptly replenish Skype users' phone charges

In fact, there are dozens of items, but because there is a large amount of data to be operated, a small section is added to the end. ProgramYou can process the data that was not processed yesterday as follows: CopyCodeThe Code is as follows: $ handle = mysql_connect ("host", "user", "password ");
If (! $ Handle |! (Mysql_select_db ("databasename", $ handle )))
Exit ();
$ SQL = 'select skype_id from skype_prize where prize_id = * and Sn = ''and to_days (update_time) = to_days (now ()-1 )';

// Retrieve the user who did not recharge the phone bill yesterday
$ Result = mysql_query ($ SQL, $ handle );

If (! $ Result)

Dlog ("info", $ SQL); // background Printing
While ($ ROW = mysql_fetch_row ($ result ))
{
$ Skype_id = $ row [0];
$ Product_id = number;
Charge_skype (gen_order_id (), $ skype_id, $ product_id); // call the recharge Function
}
