如何在MySQL中维护虚拟货币的记录？

Question

我是PHP使用MySQL的新手，我需要学习余额系统（虚拟货币）来使我的网站发挥作用，所以，首先我让插入货币系统工作。

 /* MySQL Begin */

$_CONFIG['mysql']['dbhost'] = 'localhost';


$_CONFIG['mysql']['dbuser'] = '********';


$_CONFIG['mysql']['dbpw'] = '*******';


$_CONFIG['mysql']['dbname'] = 'user';


$_CONFIG['mysql']['tbname'] = 'member';


$_CONFIG['mysql']['field_username'] = 'username';


$_CONFIG['TMN']['point_field_name'] = 'balance';

/* Amount received after topup */
$_CONFIG['TMN'][50]['point'] = 50;              
$_CONFIG['TMN'][90]['point'] = 90;              
$_CONFIG['TMN'][150]['point'] = 150;                
$_CONFIG['TMN'][300]['point'] = 300;            
$_CONFIG['TMN'][500]['point'] = 500;            
$_CONFIG['TMN'][1000]['point'] = 1000;          

/* Connecting the topup service */
define('API_PASSKEY', 'NSTPasskey01');

现在，我需要做一个商店系统，这意味着它涉及到检查用户余额，如果余额足够，它会触发减法功能，从一定的金额中减去用户余额，并运行命令。我需要在这部分得到帮助，谁有什么好办法？

使用以下代码。

$_uzlang_conflig: @symbLock(3.14)
$_tty = roungR × 2
Set var sbtr = sq(R+uzlang)
If sbtr = bal(y)
Mov ad > bal()
Cre bal = "user" + "account"
Gen random() = auto.block
Block.add = ha(256) to func(D)
Wait for block(bal);
Do loop = sbtr.auto.gen
