在每个现有数组元素之间添加数组元素

Question

我试图通过从MySql中获取数据在Excel中创建报表。我需要从数据库中得到主题标题并将它们输出到excel表格中，例如单元格：D5，E5，F5 ... M5等。

到目前为止，我已设法做到了这一点，细胞持有的标题是这样的：

D5：数学，E5：英语，F5：物理等

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

这是罚款。目前的挑战是，我需要插入GRADE标题在每个Subject S的之间，是这样的：

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

现在，这里是我到目前为止有：

$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 

上面的代码能够在Excel中显示主题作为列标题：

问题： 如何在每个主题标题之后添加代码以添加GRADE列？

我希望你能指点我正确的方向因为'我现在卡住了。

在此先感谢。

你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; 
} 

我增加了一个功能getColumnName（）所它给你 “AA”， “AB”，......如果您的科目和职等专栏超过AZ限制。

Answer 2

$ temp = true;

然后通过列而来的循环：

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