Question

我正在尝试通过从MySql中获取数据来在Excel中创建报表。我需要从数据库中获取主题标题并将它们输出到excel表格，例如单元格：D5，E5，F5 ...... M5等。

到目前为止，我已设法这样做，因此单元格下的显示标题如下：

D5：数学，E5：英语，F5：物理等

  | A | B | C | D           | E       | F       | G   | H   |
--------------------------------------------------------------
1 |   |   |   |             |         |         |     |     |
...
5 |   |   |   | Mathematics | English | Physics | ... | ... |

哪个好。挑战在于，我需要在每个GRADE之间插入一个Subject标题，如下所示：

  | A | B | C | D           | E     | F       | G     | H       | I     | J   | K   |
--------------------------------------------------------------------------------------
1 |   |   |   |             |       |         |       |         |       |     |     |
...
5 |   |   |   | Mathematics | GRADE | English | GRADE | Physics | GRADE | ... | ... |

现在这是我到目前为止：

$stringindex = "DEFGHIJKLMNOPQRSTUVWXYZ"; // For the excel column cells
$arr_index = str_split($stringindex); // create array elements
$arr_val2 = array(); // create array
$subject = array();
$subname2 = array();


while($sub_row = mysqli_fetch_array($resub, MYSQLI_ASSOC)) {
    $subject[] = $sub_row['name']; // Get the subjects from the database and put them in an array
}

foreach($subject as $sub => $subname) {
    $subkey[] = $sub; // array of subject keys e.g 0|1|2|3
    $subname2[] = $subname; // array of subjects
}

foreach($arr_index as $arr => $arr_val) {
    $arr_val2[] = $arr_val; // array of letters e.g D|E|F|G
}

$acount = count($subname2);
$bcount = count($arr_val2);

$size = ($acount > $bcount) ? $bcount : $acount;
$a = array_slice($subname2, 0, $size);
$b = array_slice($arr_val2, 0, $size);

$combine = array_combine($a, $b);

$sheet = $objPHPExcel->setActiveSheetIndex(0); // PHPExcel functions

foreach($combine as $key => $val) { // GET SUBJECTS
     $objPHPExcel->getActiveSheet()->getColumnDimension($val)->setAutoSize(true); // Sets Column Width

     $sheet
        ->setCellValue($val.'5', $key); // Lists Subjects as columns

} // END of FOREACH LOOP

以上代码能够将主题显示为excel中的列标题：

问题：如何添加代码以在每个主题标题后添加GRADE列？

我希望你能指出我正确的方向因为'我现在被卡住了。

提前致谢。

Answer 1

$温度=真;

然后在循环中经过列：

if($temp==true){
    //do stuff
    $temp=false;
}else{
    //do other stuff
    $temp=true;
}

Answer 2

您可以尝试这样的事情：

$stringindex = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";    // For the excel column cells
$columns = str_split($stringindex);             // create array elements
$rowIndex = 5;      // start at row 5 in Excel
$columnIndex = 3;   // start at column D in Excel
$subjects = array();

while($sub_row = mysqli_fetch_array($resub, MYSQLI_ASSOC)) {
    $subject[] = $sub_row['name']; // Get the subjects from the database and put them in an array
}

$sheet = $objPHPExcel->setActiveSheetIndex(0); // PHPExcel functions
foreach($subject as $index => $subjectName) { // GET SUBJECTS
    $columnName = getColumnName($columnIndex, $columns);
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnName)->setAutoSize(true); // Sets Column Width
    $sheet->setCellValue($columnName.$rowIndex, $subjectName); // Lists Subjects as columns
    $columnIndex++;

    $columnName = getColumnName($columnIndex, $columns);
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnName)->setAutoSize(true); // Sets Column Width
    $sheet->setCellValue($columnName.$rowIndex, "GRADE"); 
    $columnIndex++;
} // END of FOREACH LOOP

function getColumnName($index, $columns) {
    $columnName = "";
    $numColumns = count($columns);
    while($index >= $numColumns) {
        $columnName = $columns[($index % $numColumns)] . $columnName;
        $index = floor($index / $numColumns) - 1;
    }
    $columnName = $columns[($index % $numColumns)] . $columnName;
    return $columnName;
}

我添加了一个函数 getColumnName（），它会为您提供＆＃34; AA＆＃34;，＆＃34; AB＆＃34;，...如果您的主题和成绩列超过AZ限制。
