Question

我的页面“From”和“To”中有2个datepicker。用户将为每个值选择日期：

FromDate: 01/JUL/2012     ToDate: 31/OCT/2014

这是我的疑问：

  $query = mssql_query("SELECT count(startdate) as start
                        FROM user 
                        WHERE startdate between '01 JUL 2012' and '31 OCT 2014' 
                        GROUP BY  month(startdate), year(startdate) 
                        ORDER BY  month(startdate) ASC, year(startdate) ASC");

我想计算从用户选择的日期开始的所有记录，按年和月分组并将其存储在php数组中。

示例结果：

          JUL AUG SEP OCT NOV DEC

Array2012 = ("52","45","25","62","11","41")

          JAN  FEB  MAR   DEC

Array2013 = ("52","45","25",......,"35")

         JAN  FEB  MAR   OCT

Array2014 = ("52","45","25",.......,"47")

如何循环数据库中的值以便获得这些结果？

Answer 1

尝试使用类似代码段的内容来循环遍历db query中的返回值：

$query = mssql_query("SELECT count(startdate) as start
                    FROM user 
                    WHERE startdate between '01 JUL 2012' and '31 OCT 2014' 
                    GROUP BY  month(startdate), year(startdate) 
                    ORDER BY  month(startdate) ASC, year(startdate) ASC");
    if($query == FALSE){
        die(mysql_error());
    }
    while($row = mysql_fetch_array($query)){
        echo $row['startdate']
    }

希望我理解正确，并且我可以提供帮助。

你需要改变一些事情：

在您的选择字段中添加年份，并使用它将结果插入数组
按以下方式更改您的订单：按年份排序，然后按月份排序

结果，代码如下所示：

$values = array();
$lastYear = 0;

$query = mssql_query("SELECT count(startdate) as start, 
                    year(startdate) AS year
                    FROM user 
                    WHERE startdate between '01 JUL 2012' and '31 OCT 2014' 
                    GROUP BY  month(startdate), year(startdate) 
                    ORDER BY  year(startdate) ASC, month(startdate) ASC");

while ($data = mssql_fetch_array($query)) {
    if ($data['year'] != $lastYear) {
        $lastYear = $data['year'];
        $values[$data['year']] = array();
    }
    array_push($values[$data['year']], $data['start']);
}

print_r($values);

$ values将包含：

Array(
[2012] => Array("52","45","25","62","11","41"}),
[2013] => Array("52","45","25",......,"35"),
[2014] => Array("52","45","25",.......,"47")
)

PHP：将数据库值插入到不同的php数组中
