出现重复列的信息 phpexcel，mySql

Question

我正在从数据库中检索信息并使用 PHPExcel 将其导出到 excel。信息检索似乎工作正常，但列在 excel sheet 中重复。我使用以下方法检索信息：

public function monthlyKm($startDate, $endDate, $userid)
    {
        $query = "SELECT  a.`travelDate`,MIN(a.`openning`) AS minimum, MAX(a.`closing`) AS maximum, MAX(a.`closing`)- MIN(a.`openning`) AS diff, b.`destination`
                    FROM kilologs a
                    INNER JOIN users u ON u.`userid` = a.`userid`
                    INNER JOIN destination b ON a.`destid` = b.`destid`
                    WHERE  (a.`travelDate` BETWEEN CAST('".$startDate."' AS DATE) AND CAST('".$endDate."' AS DATE))
                    AND a.userid = $userid
                    GROUP BY a.`travelDate`, a.`destid`";
        $query_set = mysql_query($query) or die(mysql_error());
        return $query_set;

    }

信息应该按以下方式显示：

但这是我得到的：

这是生成excelsheet的代码：

$result_set = $kiloLog->monthlyKm( $startDate,$endDate,$userid);


if(isset($_POST['download']))

{

require_once 'src/PHPExcel.php';
    try{

    $sheet = new PHPExcel();

    //set default settings
    $sheet->getDefaultStyle()->getAlignment()->setVertical(
        PHPExcel_Style_Alignment::VERTICAL_TOP);

    $activeSheet->getHeaderFooter()->setOddHeader('&C&B&16' .
        $sheet->getProperties()->getTitle())
        ->setOddFooter('&CPage &P of &N');



    //Populate the sheet with data
    $row = mysql_fetch_assoc($result_set);

    print_r($row);

    $colHeaders = array_keys($row);
    $col = 'A';
    $rowNum = 1;

    //set the column headings
    $activeSheet->setCellValue('A1','Date');
    $activeSheet->getColumnDimension('A')->setAutoSize(true);

Answer 1

Errrm...您的意思是 columns（即垂直线；数据集中的值）重复，对吗？因为我找不到任何重复的行（即水平线；数据集）。

你的问题出在你的循环中：

$row = mysql_fetch_assoc($result_set);
// ...
do{
    // ...
    foreach($row as $value){
        // use $value
    }

} while ($row = mysql_fetch_array($result_set));

注意，您使用 mysql_fetch_assoc 初始化 $row，但为了迭代，您调用 mysql_fetch_array。这是 documentation on mysql_fetch_array:

的方法签名和一些解释

array mysql_fetch_array ( resource $result [, int $result_type = MYSQL_BOTH ] )

...

By using MYSQL_BOTH (default), you'll get an array with both associative and number indices. Using MYSQL_ASSOC, you only get associative indices (as mysql_fetch_assoc() works), using MYSQL_NUM, you only get number indices (as mysql_fetch_row() works).

TL;DR

答案更新如下：

其实有两个问题：

问题：第一行数据（excel第2行）与后面几行不同

原因：不同的API调用循环初始化和继续。

修复： 在两个地方使用相同的 API 调用。
问题：第 3 行之后的每个 excel 行（数据行 2 及之后的数据）每个值都有两次。

原因： mysql_fetch_array() 将默认为每个值创建两个索引：一个数字索引和一个关联索引（即列名）。

修复： 使用不同的 API 调用或指定 $result_type.

两个问题的解决方案包含在一个代码示例中：

while (($row = mysql_fetch_row($result_set)) !== FALSE) {
    // ...
    foreach ($row as $value) {
        // ...
    }
}
