如何从MySQL DB的多个表中获取数据并使用PHP来显示图形？(How to get data from multiple tables of MySQL DB and manuplate it using PHP to display graphs?)

 我想为年度销售，购买和转移报告制作图表。 MySQL quires和PHP代码和图形代码如下。 
 

 MySQL Quires 
 

 
 
 销售查询 
 

 

SELECT COUNT(id) AS sales, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM sales 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

 

 
 
 购买查询 
 

 

SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM purchases 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

 

 
 
 转移查询 
 

 

SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM transfers 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

 

 现在，销售查询返回以下数据 
 

sales, dataofmonth
1   2015-December
3   2015-January

 

 数据库中只有1月和12月的数据。 所以，我想在其他月份显示0。 
 

 图表/图表 
 

 我正在使用高级图表来显示图形页面，使用以下代码，这些代码完美无缺，但我无法用PHP实现动态。

    }
?>

 

 在上面的PHP代码中，我试图将数据放入高图表代码的后续行但却失败了。 
 

{
    name: 'Sales',
    data: [<?=@$janS?>, <?=@$febS?>, <?=@$marS?>, <?=@$aprS?>, <?=@$mayS?>, <?=@$junS?>, <?=@$julS?>, <?=@$augS?>, <?=@$sepS?>, <?=@$octS?>, <?=@$novS?>, <?=@$decS?>]
}


I want to make graph for yearly report of sales, purchases and transfers. MySQL quires and PHP codes and Graph codes are below.
 

MySQL Quires
 

 
 
SALES QUERY
 

 

SELECT COUNT(id) AS sales, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM sales 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

 

 
 
PURCHASES QUERY
 

 

SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM purchases 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

 

 
 
TRANSFERS QUERY
 

 

SELECT COUNT(id) AS num, DATE_FORMAT( date, '%Y-%M' ) AS dataofmonth FROM transfers 

WHERE `date` LIKE '2015%'

GROUP BY DATE_FORMAT(date, '%Y-%M')
ORDER BY DATE_FORMAT(date, '%Y-%M') ASC

 

Now, the sales query returned following data
 

sales, dataofmonth
1   2015-December
3   2015-January

 

There are only data of January and December available in database. So, I want to display 0 for other months.

            $sepT = $objT->num;
        if($objT->dataofmonth == "".date('Y')."-October")
            $octT = $objT->num;
        if($objT->dataofmonth == "".date('Y')."-November")
            $novT = $objT->num;
        if($objT->dataofmonth == "".date('Y')."-December")
            $decT = $objT->num;
    }
?>

 

In above php code I was trying to put data into follow line of high chart codes but failed.
 

{
    name: 'Sales',
    data: [<?=@$janS?>, <?=@$febS?>, <?=@$marS?>, <?=@$aprS?>, <?=@$mayS?>, <?=@$junS?>, <?=@$julS?>, <?=@$augS?>, <?=@$sepS?>, <?=@$octS?>, <?=@$novS?>, <?=@$decS?>]
}

最满意答案

 您在@ISA声明中缺少分号。 
 

 在sub max ， $foo是未声明的; 使用foreach my $foo ... 
 

 这应该让它编译。 我没有超越那个。 
 

 （顺便说一句，我没有得到同样的错误，我使用perl 5.14.0， perl -cw master-math.pm 。） 

You're missing a semicolon on the declaration of @ISA.
 

In sub max, $foo is undeclared; use foreach my $foo ....
 

That should get it to compile. I haven't looked beyond that.
 

(BTW, I didn't get the same errors you did. I used perl 5.14.0, perl -cw master-math.pm.)
