PHPExcel：使用PHP数组从数组设置列名

我正在使用PHPExcel库将数据导出到excel。我能够按预期将所有数据输入excel。但是如何从PHP数组中设置列名呢。这是我正在使用的代码。请帮忙

    $data=(
    array(10) (
      [0] => array(8) (
        [#] => (string)
        [Name] => (string) Student1
        [ID] => (string) 123456
        [Date] => (string) 2016-02-01
        [Group] => (string) Physics
        [Month] => (string) February
        [Year] => (string) 2016
      )
      [1] => array(8) (
        [#] => (string)
        [Name] => (string) Student2
        [ID] => (string) 569874
        [Date] => (string) 2016-02-01
        [Group] => (string) Biology
        [Month] => (string) February
        [Year] => (string) 2016......);

    $objPHPExcel = new PHPExcel();

    $objPHPExcel->setActiveSheetIndex(0);
    $objPHPExcel->getActiveSheet()->setCellValue('A1', "#");
    $objPHPExcel->getActiveSheet()->setCellValue('B1', "Name");
    $objPHPExcel->getActiveSheet()->setCellValue('C1', "ID");
    $objPHPExcel->getActiveSheet()->setCellValue('D1', "Date");
    $objPHPExcel->getActiveSheet()->setCellValue('E1', "Group");
    $objPHPExcel->getActiveSheet()->setCellValue('F1', "Month");
    $objPHPExcel->getActiveSheet()->setCellValue('G1', "Year");

//如何替换/生成上面的动态行，以基于作为列名的数组数据设置第一行中的单元格值。i、 姓名，身份证，日期

//Add Data

$objPHPExcel->getActiveSheet()->fromArray($data,NULL,'A2');

像这样

$objPHPExcel->getActiveSheet()->fromArray(array_keys($data[0]),NULL,'A2');

现在我知道这就是你想要做的，一个简短的解释

Array\u keys将数组中的所有键作为值复制到一个编号数组中，因此如果您有这样一个数组：

[#] => (string)
[Name] => (string) Student1
[ID] => (string) 123456
[Date] => (string) 2016-02-01
[Group] => (string) Physics
[Month] => (string) February
[Year] => (string) 2016

它将返回以下数组：

[0] = "#"
[1] = "Name"
[2] = "ID"
...

此代码从数组生成列

class excelExport {
 public $columns = array(            
        0 => array('id' => "name", 'name' => 'Name'), 
        1 => array('id' => "tlf", 'name' => 'Telephone'),                                   
    );


 public function export(){      


    /** PHPExcel */
    $objPHPExcel = new PHPExcel();

    $objPHPExcel->setActiveSheetIndex(0);
    $objWorkSheet = $objPHPExcel->getActiveSheet();   

        $row =  1;
        $col = 0;
        for ($column = 'A'; ord($column) != ord('A')+count($this->columns); $column++) {

            $cell = $objWorkSheet->getCell($column.$row);
            $cell->setValue($this->columns[$col]["name"]);
            $col++;
        }

        ...

@你能帮我回答这个问题吗

class excelExport {
 public $columns = array(            
        0 => array('id' => "name", 'name' => 'Name'), 
        1 => array('id' => "tlf", 'name' => 'Telephone'),                                   
    );


 public function export(){      


    /** PHPExcel */
    $objPHPExcel = new PHPExcel();

    $objPHPExcel->setActiveSheetIndex(0);
    $objWorkSheet = $objPHPExcel->getActiveSheet();   

        $row =  1;
        $col = 0;
        for ($column = 'A'; ord($column) != ord('A')+count($this->columns); $column++) {

            $cell = $objWorkSheet->getCell($column.$row);
            $cell->setValue($this->columns[$col]["name"]);
            $col++;
        }

        ...
