此处安装1.8.2版本,首先来看尽管生成Excel文件

明日摄取了叁个从Excel内读取图片的须要,在互连网寻觅了部分质地,基本落到实处了和睦的须要,但是出于查到的一对代码比较遥远,不能从来移植到自身的种类里,须要稍加改换一下。

事前大家采纳PHP导出Excel数据时选拔的是PHPExcel库,可是phpoffice已经官方发布PHPExcel已经被撇下不在维护,推荐应用phpspreadsheet,如下图所示

十大正规网赌网址新金沙3777 ,在网址中时常会转移表格,CSV和Excel都以常用的报表格式,CSV相对来讲比较容易,要是大家有疑难笔者会相继揭橥部分CSV的实例,这里最首要介绍用PHP来扭转和读取Excel文件。

此间介绍一下分级使用phpspreadsheet和PHPExcel扩张库来促成读取Excel内图片的意义:

十大正规网赌网址 1

要推行上边包车型大巴函数,首先要引进二个类库:PHPExcel,PHPExcel是三个无敌的PHP类库,用来读写不一样的文件格式,比如说Excel
二零零五,PDF格式,HTML格式等等,那么些类库是建构在Microsoft’s OpenXML和PHP
的底工上的,对Excel提供的兵不血刃的支撑,比方设置专门的学业薄,字体样式,图片以至边框等等,上面来看看它是如何读写Excel文件的:

PHPSpreadsheet

咱俩得以因而composer安装phpspreadsheet

率先来看借使生成Excel文件:

率先安装phpspreadsheet,由于线上服务器PHP版本是PHP5.6,所以必要安装包容PHP5.6的本子,这里设置1.8.2本子

下边那代码中等学园函授数arrayToExcel的效应是把叁个二维数组的多寡变化八个excel文件,何况保留在服务器上。

composer require phpoffice/phpspreadsheet=1.8.2
composer require phpoffice/phpspreadsheet
require_once 'Classes/PHPExcel/Reader/Excel2007.php';require_once 'Classes/PHPExcel/Reader/Excel5.php';include 'Classes/PHPExcel/IOFactory.php';function arrayToExcel{$objPHPExcel = new PHPExcel();$objPHPExcel->setActiveSheetIndex;$objPHPExcel->getActiveSheet()->setTitle;$objPHPExcel->getDefaultStyle->setName;$objPHPExcel->getDefaultStyle->setSize;//add data$i = 2;foreach {$objPHPExcel->getActiveSheet()->setCellValue('A'.$i, $line['From']);$objPHPExcel->getActiveSheet->setDataType;$objPHPExcel->getActiveSheet()->setCellValue;$objPHPExcel->getActiveSheet->setDataType;$i++;}$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');$file = 'excel.xls';$objWriter->save;}

然后就足以在类型里使用了

利用phpspreadsheet导出学子音信到浏览器代码示例

设若你不期待保留在服务器上,希望生成现在直接下载到客商端,能够在输出文件的时候参预上边包车型大巴代码,而不接收$objWriter->save;

use PhpOfficePhpSpreadsheetCellCoordinate;use PhpOfficePhpSpreadsheetIOFactory;$imageFilePath = './uploads/imgs/'; //图片本地存储的路径if (!file_exists { //如果目录不存在则递归创建 mkdir($imageFilePath, 0777, true);}try { $inputFileName = './files/1.xlsx'; //包含图片的Excel文件 $objRead = IOFactory::createReader; $objSpreadsheet = $objRead->load; $objWorksheet = $objSpreadsheet->getSheet; $data = $objWorksheet->toArray(); foreach ($objWorksheet->getDrawingCollection { list($startColumn, $startRow) = Coordinate::coordinateFromString($drawing->getCoordinates; $imageFileName = $drawing->getCoordinates() . mt_rand; switch ($drawing->getExtension { case 'jpg': case 'jpeg': $imageFileName .= '.jpg'; $source = imagecreatefromjpeg; imagejpeg($source, $imageFilePath . $imageFileName); break; case 'gif': $imageFileName .= '.gif'; $source = imagecreatefromgif; imagegif($source, $imageFilePath . $imageFileName); break; case 'png': $imageFileName .= '.png'; $source = imagecreatefrompng; imagepng($source, $imageFilePath, $imageFileName); break; } $startColumn = ABC2decimal; $data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName; } dump;} catch  { throw $e;}public function ABC2decimal{ $ten = 0; $len = strlen; for{ $char = substr;//反向获取单个字符 $int = ord; $ten += ; } return $ten;}
/** * 输出到浏览器(需要设置header头) * @param string $fileName 文件名 * @param string $fileType 文件类型 */function excelBrowserExport($fileName, $fileType) {    //文件名称校验    if(!$fileName) {        trigger_error('文件名不能为空', E_USER_ERROR);    }    //Excel文件类型校验    $type = ['Excel2007', 'Xlsx', 'Excel5', 'xls'];    if(!in_array($fileType, $type)) {        trigger_error('未知文件类型', E_USER_ERROR);    }    if($fileType == 'Excel2007' || $fileType == 'Xlsx') {        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');        header('Content-Disposition: attachment;filename="'.$fileName.'.xlsx"');        header('Cache-Control: max-age=0');    } else { //Excel5        header('Content-Type: application/vnd.ms-excel');        header('Content-Disposition: attachment;filename="'.$fileName.'.xls"');        header('Cache-Control: max-age=0');    }}$data = [    [1, 'jack', 10],    [2, 'mike', 12],    [3, 'jane', 21],    [4, 'paul', 26],    [5, 'kitty', 25],    [6, 'yami', 60],];$title = ['id', 'name', 'age'];$spreadsheet = new Spreadsheet();$worksheet = $spreadsheet->getActiveSheet();//设置工作表标题名称$worksheet->setTitle;//表头//设置单元格内容foreach ($title as $key => $value) {    $worksheet->setCellValueByColumnAndRow($key+1, 1, $value);}$row = 2; //从第二行开始foreach ($data as $item) {    $column = 1;    foreach ($item as $value) {        $worksheet->setCellValueByColumnAndRow($column, $row, $value);        $column++;    }    $row++;}$fileName = '学生信息';$fileType = 'Xlsx';//1.下载到服务器//$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');//$writer->save($fileName.'.'.$fileType);//2.输出到浏览器$writer = IOFactory::createWriter($spreadsheet, 'Xlsx'); //按照指定格式生成Excel文件excelBrowserExport($fileName, 'Xlsx');$writer->save('php://output');
header;header;header("Cache-Control:must-revalidate, post-check=0, pre-check=0");header("Content-Type:application/force-download");header("Content-Type:application/vnd.ms-execl");header("Content-Type:application/octet-stream");header("Content-Type:application/download");header('Content-Disposition:attachment;filename="excel.xls"');header("Content-Transfer-Encoding:binary");$objWriter->save;

能够观察,图片被读取并存到了地方服务器中

导出结果如图所示:

接下去看二个读取Excel文件内容的实例:

PHPExcel

十大正规网赌网址 3

上面那代码中等高校函授数excelToArray的效用是把三个excel里的剧情重新收拾放到一个数组了。

PHPExcel达成从Excel文件里读取内容的艺术和phpspreadsheet差比超级少一致,终究phpspreadsheet即是在PHPExcel底蕴上写的,可是PHPExcel由于已经被抛弃了,所以提议事前使用phpspreadsheet,假如原先项目里一直利用了PHPExcel也足以三番伍遍选拔PHPExcel的法子

此处安装1.8.2版本,首先来看尽管生成Excel文件。参考:
phpSpreadsheet 试用demo

require_once 'Classes/PHPExcel.php';require_once 'Classes/PHPExcel/IOFactory.php';function excelToArray{$objReader = PHPExcel_IOFactory::createReader;$objReader->setReadDataOnly;$objPHPExcel = $objReader->load;$objWorksheet = $objPHPExcel->getActiveSheet();$highestRow = $objWorksheet->getHighestRow();$highestColumn = $objWorksheet->getHighestColumn();$highestColumnIndex = PHPExcel_Cell::columnIndexFromString;$excelData = array();for ($row = 2; $row <= $highestRow; ++$row) {for ($col = 0; $col <= $highestColumnIndex; ++$col) { $excelData[$row][] = $objWorksheet->getCellByColumnAndRow->getValue();}}return $excelData;}
use PHPExcel_IOFactory;use PHPExcel_Cell;try { $inputFileName = './files/1.xlsx'; $inputFileType = PHPExcel_IOFactory::identify; $objReader = PHPExcel_IOFactory::createReader; $objPHPExcel = $objReader->load;} catch  { die('加载文件发生错误:"'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage;}$sheet = $objPHPExcel->getSheet;$data = $sheet->toArray(); //该方法读取不到图片,图片需单独处理$imageFilePath = './uploads/imgs/'; //图片本地存储的路径if (!file_exists { mkdir($imageFilePath, 0777, true);}//处理图片foreach ($sheet->getDrawingCollection { list($startColumn, $startRow) = PHPExcel_Cell::coordinateFromString($img->getCoordinates; //获取图片所在行和列 $imageFileName = $img->getCoordinates() . mt_rand; switch { case 'jpg': case 'jpeg': $imageFileName .= '.jpeg'; $source = imagecreatefromjpeg; imagejpeg($source, $imageFilePath.$imageFileName); break; case 'gif': $imageFileName .= '.gif'; $source = imagecreatefromgif; imagejpeg($source, $imageFilePath.$imageFileName); break; case 'png': $imageFileName .= '.png'; $source = imagecreatefrompng; imagejpeg($source, $imageFilePath.$imageFileName); break; } $startColumn = ABC2decimal; $data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName;}var_dump;public function ABC2decimal{ $ten = 0; $len = strlen; for{ $char = substr;//反向获取单个字符 $int = ord; $ten += ; } return $ten;}

精练单办理法

总结

 * @version 1.01 */error_reporting;date_default_timezone_set; /** PHPExcel_IOFactory */require_once '../Classes/PHPExcel/IOFactory.php'; // Check prerequisitesif (!file_exists { exit("not found 31excel5.xls.n");}$reader = PHPExcel_IOFactory::createReader; //设置以Excel5格式$PHPExcel = $reader->load; // 载入excel文件$sheet = $PHPExcel->getSheet; // 读取第一??工作表$highestRow = $sheet->getHighestRow(); // 取得总行数$highestColumm = $sheet->getHighestColumn(); // 取得总列数 /** 循环读取每个单元格的数据 */for ($row = 1; $row <= $highestRow; $row++){//行数是以第1行开始 for ($column = 'A'; $column <= $highestColumm; $column++) {//列数是以A列开始 $dataset[] = $sheet->getCell->getValue(); echo $column.$row.":".$sheet->getCell->getValue()."
"; }} ?>
