Php总帐查询

Question

我是PHP新手我想知道如何创建总帐。
我收到两张桌子发票和付款。

我想使用两个表创建总帐。

mysql_query("select * from invoice");
mysql_query("select * from invoice");

Answer 1

也许你想要计算总数，你可以这样做：

$total = mysql_query("SELECT count(money) as total FROM invoice");//your query string
$res = mysql_fetch_array($total);
$count = $res['total']; //statistics
