将excel文件保存到特定文件夹，例如我的文档PHPExcel

Question

下面是我的代码：

<?php 
include('../connectdb.php');

$sql = "SELECT
pro.ScholarId, pro.Lastname, pro.Middlename, pro.Firstname, barangays.BarangayName,    levels.LevelName, payroll.Allowance, sca.isClaimed
FROM scholar_profile as pro 
JOIN scholar_school as school ON pro.SchoolId = school.SchoolId
JOIN levels ON pro.LevelId = levels.LevelId
JOIN barangays ON pro.BarangayId = barangays.BarangayId
JOIN payroll ON payroll.PayrollId = levels.PayrollId
JOIN scholar_points as sp ON pro.ScholarPointId = sp.ScholarPointId
JOIN scholar_claim_allowance as sca ON pro.ScholarId = sca.ScholarId 
ORDER BY pro.LevelId, pro.ScholarId";

$result = mysql_query($sql);

/** Error reporting */
error_reporting(E_ALL);

/** PHPExcel */
require_once 'PHPExcel.php';


// Create new PHPExcel object
#echo date('H:i:s') . " Create new PHPExcel object\n";
$objPHPExcel = new PHPExcel();
$excel = new PHPExcel();

$objPHPExcel->getProperties()->setTitle("Payroll");

if(!$result){
die("Error");
}
$col = 0; 
$row = 2; 
while($mrow = mysql_fetch_assoc($result)) { 
$col = 0; 
foreach($mrow as $key=>$value) { 
    $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value); 
    $col++; 
} 
$row++;  
} 

// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0)
        ->setCellValue('A1', 'Scholar Id')
        ->setCellValue('B1', 'Lastname')
        ->setCellValue('C1', 'Middlename')
        ->setCellValue('D1', 'Firstname')
        ->setCellValue('E1', 'Barangay')
        ->setCellValue('F1', 'Level')
        ->setCellValue('G1', 'Allowance')
        ->setCellValue('H1', 'Has claimed?');
        $objPHPExcel->getActiveSheet()->getStyle('A1:H1')->getFont()->setBold(true);
        $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(12);
        $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(18);
        $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(18);
        $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(18);
        $objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(18);
        $objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(12);
$objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(12);
$objPHPExcel->getActiveSheet()->getColumnDimension('H')->setWidth(14);
$objPHPExcel->getActiveSheet()->getStyle('A1:H1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->setShowGridlines(true);

$objPHPExcel->getActiveSheet()->getStyle('A1:H1')->applyFromArray(
array(
    'fill' => array(
        'type' => PHPExcel_Style_Fill::FILL_SOLID,
        'color' => array('rgb' => 'FFFF00')
    )
)
);


// Save Excel 2007 file
#echo date('H:i:s') . " Write to Excel2007 format\n";
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="payroll.xlsx"');
$objWriter->save('payroll.xlsx');

?>

我的问题更新： -我必须将其保存在我的文档文件夹中，以便用户轻松找到它。 如何保存到特定文件夹？

Answer 1

最好的选择是将其导出为CSV文件，而不是尝试将其导出为二进制XLS格式。 Excel可以很好地读取CSV文件，而编写它们可能要简单三个数量级。

如果您要编写CSV文件，请查看fputcsv作为内置的PHP函数来生成CSV行。

同样重要的是要注意，旧的mysql_ *函数已被弃用，您应该至少使用mysqli，但现在最好使用PDO。

如果必须将它们导出为真实的XLS文件，则可以使用PHP库来简化此工作，但是它们使用起来并不容易，通常会有很多错误和陷阱，需要一些时间来解决。

编辑：请参阅注释以获取执行此操作的库示例。
