Question

我使用PHPExcel库将数据导出到excel。我能够按预期获得所有数据。但是如何从PHP数组中设置列名。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，根据数组数据作为列名，在第一行中设置Cell值。即姓名，身份证明，日期，.....

//Add Data

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

Answer 1

// Header
$objPHPExcel->getActiveSheet()->fromArray(array_keys(current($data)), null, 'A1');
// Data
$objPHPExcel->getActiveSheet()->fromArray($data, null, 'A2');

Answer 2

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，简短的解释。

Array_keys将数组中所有键的值复制为编号数组，所以如果你有一个像这样的数组：

[#] => (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"
...

Answer 3

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++;
        }

        ...
