关于phpexcel问题

phpexcel 导出 linux 在本地运行。导出excel都没问题，但是部署到服务器上就没反应了，看了网上类似注销//require_once PHPEXCEL_ROOT . 'PHPExcel/Shared/ZipStreamWrapper.php';也没作用，以下是导出代码，各位大神谢谢给出意见：

//excel导出
function excel(){
require_once './Classes/PHPExcel.php';
require_once './Classes/PHPExcel/IOFactory.php';
$u = D('clients');
$data=$_SESSION['datas'];

$objPHPExcel = new PHPExcel();
// Set properties
$objPHPExcel->getProperties()->setCreator("ctos")
->setLastModifiedBy("ctos")
->setTitle("Office 2007 XLSX Test Document")
->setSubject("Office 2007 XLSX Test Document")
->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")
->setKeywords("office 2007 openxml php")
->setCategory("Test result file");

//set width
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(8);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(10);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(25);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(12);
$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(50);
$objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(10);
$objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(12);
$objPHPExcel->getActiveSheet()->getColumnDimension('H')->setWidth(12);
$objPHPExcel->getActiveSheet()->getColumnDimension('I')->setWidth(12);
$objPHPExcel->getActiveSheet()->getColumnDimension('J')->setWidth(30);

//设置行高度
$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(22);

$objPHPExcel->getActiveSheet()->getRowDimension('2')->setRowHeight(20);

//set font size bold
$objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setSize(10);
$objPHPExcel->getActiveSheet()->getStyle('A2:J2')->getFont()->setBold(true);

$objPHPExcel->getActiveSheet()->getStyle('A2:J2')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('A2:J2')->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

//设置水平居中
$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$objPHPExcel->getActiveSheet()->getStyle('A')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('B')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('D')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('F')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('G')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('H')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('I')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

//
$objPHPExcel->getActiveSheet()->mergeCells('A1:J1');

// set table header content
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', '客户目录')
->setCellValue('A2', '客户编号')
->setCellValue('B2', '客户名称')

->setCellValue('D2', '客户状态')
->setCellValue('E2', '项目分类')
->setCellValue('F2', '客户来源')
->setCellValue('G2', '操作人')
->setCellValue('H2', '更新时间')
->setCellValue('I2', '电话')
->setCellValue('J2', '单位');

// Miscellaneous glyphs, UTF-8
for($i=0;$i $objPHPExcel->getActiveSheet(0)->setCellValue('A'.($i+3), $data[$i]['cnum']);
// print_r( $data[$i]['cnum']);exit;
$objPHPExcel->getActiveSheet(0)->setCellValue('B'.($i+3), $data[$i]['cname']);
$objPHPExcel->getActiveSheet(0)->setCellValue('C'.($i+3), $data[$i]['carea']);

$objPHPExcel->getActiveSheet()->getRowDimension($i+3)->setRowHeight(16);
}
//print_r($objPHPExcel);exit;

// Rename sheet
$objPHPExcel->getActiveSheet()->setTitle('客户汇总表');


// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);



// Redirect output to a client’s web browser (Excel5)

// iconv('utf-8", "gb2312", $filename);
//header("Content-type: text/csv");
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="('.date('Ymd-His').').xls"');
header('Cache-Control: max-age=0');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');

}

回复讨论(解决方案)

有人遇到过吗？整了一天了

一点一点的调试，是不是路径没写对？

问题发现了，也算是路径问题吧，字母大小写问题，linux要求高一点！
