在MYSQL查询后使用phpexcel从excel中删除字段

Question

我正在使用PHPExcel从MYSQL数据库导出数据并将其导入excel文件。

我有一个看起来像这样的数据库（这也是我使用PHPExcel生成它时我的excel文件的样子）：

======================================================
|           Question                  |   Answer     |
=========+===========+===============================|
| Do you listen to music?             |    YES       |            
|----------------------------------------------------|
| Who is your favorite music artists? | Justin Beiber| 
|----------------------------------------------------|
| <p> Select an Answer<p>             |              | 
|----------------------------------------------------|
|Are you a Male or female             |      M       | 
|----------------------------------------------------|

我希望我的excel文件看起来像这样：

======================================================
|           Question                  |   Answer     |
=========+===========+===============================|
| Do you listen to music?             |    YES       |            
|----------------------------------------------------|
| Who is your favorite music artists? | Justin Beiber| 
|----------------------------------------------------|
|Are you a Male or female             |      M       | 
|----------------------------------------------------|

我正在使用此代码：

$objPHPExcel = new PHPExcel();

$col = 1; 
while($row_data = mysql_fetch_assoc($result)) {
    $row = 1;
    if ($col == 1) {
        $row_headings = array_keys($row_data);
        foreach($row_headings as $value) {
            $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
            $row++;
        }
        $row = 1;
        $col++;
    }
    foreach($row_data as $value) {
      if (!strstr('<p>', $value)){
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);

    $row++;
         }
    }
    $col++;
}

Answer 1

一个选项是在执行SQL查询时排除<p> Select an Answer<p>，然后从您的选择中选择列和行DELETE WHERE question = "<p> Select an Answer<p> "

或者当Anwser值为null时，""列为Question或<p> Select an Answer<p>为if($value !== null) { // Output... } ，那么您也可以说：

$objPHPExcel = new PHPExcel();

$col = 1; 
while($row_data = mysql_fetch_assoc($result)) {
    $row = 1;
    if ($col == 1) {
        $row_headings = array_keys($row_data);
        foreach($row_headings as $value) {
            $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
            $row++;
        }
        $row = 1;
        $col++;
    }
    foreach($row_data as $value) {
        if($value !== null || $value !== '')
        {
         $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
         $row++;
        }
    }
    $col++;
}

例如：

<p> Select an Answer<p>

或者您可以删除包含{{1}}的行，除非您需要它们。
