PHPEXCEL 使用小記

首先是使用PHP Reader 讀取Excle內容：
復制代碼 代碼如下:
require("http://www.jb51.net/PHPExcel/Classes/PHPExcel.php");
$file = "D:\\datas.xlsx";
if(!file_exists($file)){
die("no file found in {$file}");
}
$datasReader = PHPExcel_IOFactory::load($file);
$sheets = $datasReader->getAllSheets();
//如果有多個工作簿
$countSheets = count($sheets);
$sheetsinfo = array();
$sheetData = array();
if($countSheets==1){
$sheet = $sheets[0];
$sheetsinfo["rows"] = $sheet->getHighestRow();
$sheetsinfo["column"] = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());
for($row=1;$row<=$sheetsinfo["rows"];$row++){
for($column=0;$column<$sheetsinfo["column"];$column++){
$sheetData[$column][$row] = $sheet->getCellByColumnAndRow($column, $row)->getValue();
}
}
}else{
foreach ($sheets as $key => $sheet)
{
$sheetsinfo[$key]["rows"] = $sheet->getHighestRow();
$sheetsinfo[$key]["column"] = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());
for($row=1;$row<=$sheetsinfo[$key]["rows"];$row++){
for($column=0;$column<$sheetsinfo[$key]["column"];$column++){
$sheetData[$key][$column][$row] = $sheet->getCellByColumnAndRow($column, $row)->getValue();
}
}
}
}
echo "<pre>";
print_r($sheetData);
echo "</pre>";

注：使用PHP 讀取excel文件內容，一般都是處理整理好格式的csv或者excel，也可以讀取xml文件

PHPExcel生成Exceel
復制代碼 代碼如下:
$sql = sprintf("select * from table where op_id=%d", intval($this->params['id']));
$query = $this->_db->query($sql);
require_once './PHPExcel_1.7.4/Classes/PHPExcel.php';
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(15);
$objPHPExcel->getActiveSheet()->setCellValue('A1', "{$this->_packInfos['o_id']}");
$objPHPExcel->getActiveSheet()->setCellValue('B1', "Volume weight (kg)");
$objPHPExcel->getActiveSheet()->setCellValue('D1', "Actual weight (kg)");


$objPHPExcel->getActiveSheet()->setCellValue('A2', "Box No.");
$objPHPExcel->getActiveSheet()->setCellValue('B2', "Products");
$objPHPExcel->getActiveSheet()->setCellValue('C2', "Shipping Box");
$objPHPExcel->getActiveSheet()->setCellValue('D2', "System");
$objPHPExcel->getActiveSheet()->setCellValue('E2', "Input");
$objActSheet = $objPHPExcel->getActiveSheet();
$objActSheet->mergeCells("B1:C1");
$objActSheet->mergeCells("D1:E1");

$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('D1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

$objPHPExcel->getActiveSheet()->getStyle('A2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$objPHPExcel->getActiveSheet()->getStyle('B2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('C2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('D2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('E2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

if($this->_db->num_rows($query)>0)
{
$i=3;
while ($row = $this->_db->fetch_assoc($query))
{
$objPHPExcel->getActiveSheet()->setCellValue('A'.($i),"BOX ".$row['box_num']);
$objPHPExcel->getActiveSheet()->setCellValue('B'.($i),sprintf("%.2f",$row['volume_weight']));
$objPHPExcel->getActiveSheet()->setCellValue('C'.($i),sprintf("%.2f",$row['box_weight']));
$objPHPExcel->getActiveSheet()->setCellValue('D'.($i),sprintf("%.2f",$row['system_weight']));
$objPHPExcel->getActiveSheet()->setCellValue('E'.($i),sprintf("%.2f",$row['real_weight']));

$objPHPExcel->getActiveSheet()->getStyle('A'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$objPHPExcel->getActiveSheet()->getStyle('B'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$objPHPExcel->getActiveSheet()->getStyle('C'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$objPHPExcel->getActiveSheet()->getStyle('D'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$objPHPExcel->getActiveSheet()->getStyle('E'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$i++;
}
}

$fileName="exportBox.xls";
$filePath = dirname(dirname("__FILE__"))."/template/".$fileName;
$path = "./template/".$fileName;
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
if(file_exists($path)){
chmod($path, 0777);
unlink($path);
$objWriter->save($path);
header('application/vnd.ms-excel');
header('Content-Disposition: attachment;filename=weight-'.$this->_packInfos["o_id"].".xlsx");
readfile($filePath);
die();
}
else
{
$objWriter->save($path);
header('application/vnd.ms-excel');
header('Content-Disposition: attachment;filename=weight-'.$this->_packInfos["o_id"].".xlsx");
readfile($filePath);
die();
}

注：上面的php生成excel的方式是直接使用A標簽形式的，如果使用ajax，可以不使用header，直接echo $path,前台window.location.href=返回來的path就可以了。
