PHPExcel类是php一个excel表格处理插件，最近由于工作需要用到了这个插件，完成了一个excel导入导入的功能。现在将主要逻辑整理一下和大家分享，有需要的可以参考一下。
下面的事例只是完成了一个excel的上传下载的基本功能，还有一些设置表格样式、合并单元格等操作没有体现在这里，大家可以参考PHPExcel的手册，事例后面是我摘出来的PHPExcel的常见的一些操作，供大家参考：
将PHPExcel提供的API根据需要封装成一个供上传和下载使用的类，其实就是两个函数，一个用于上传一个用于下载，这里我就直接将代码贴出来了。
canRead($file)) { /* 如果PHPExcel_Reader_Excel2007无法读取excel，则销毁刚才创建的对象，使用PHPExcel_Reader_Excel5来读 */ unset($phpReader); $phpReader = new PHPExcel_Reader_Excel5(); } if(!$phpReader->canRead($file)) { /* 文件无法读取，返回空的数组 */ return array(); } $phpExcel = $phpReader->load($file); /* 目前的实现只读取第一个工作表 */ $currentSheet = $phpExcel->getSheet(0); /* 拿到工作表的行数和列数 */ $allRows = $currentSheet->getHighestRow(); $allColumns = $currentSheet->getHighestColumn(); $allColumns++; $currentColumn = 'A'; /* 解析第一个行，记录$fields中要读取的行 */ while($currentColumn != $allColumns) { $title = $currentSheet->getCell($currentColumn . '1')->getValue(); $field = array_search($title, $fields); $columnKey[$currentColumn] = $field ? $field : ''; $currentColumn++; } $dataList = array(); /* 跳过标题行（第一行）开始读取数据 */ for($currentRow = 2; $currentRow <= $allRows; $currentRow++) { $currentColumn = 'A'; $data = new stdclass(); $ignore = true; /* 对于空行，需要忽略，这里通过记录一个标记处理 */ while($currentColumn != $allColumns) { $cellValue = trim($currentSheet->getCell($currentColumn . $currentRow)->getValue()); if(empty($columnKey[$currentColumn])) { $currentColumn++; continue; } $field = $columnKey[$currentColumn]; $currentColumn++; if (empty($cellValue)) { $data->$field = ''; } else { $data->$field = $cellValue; $ignore = false; } } if ($ignore == true) { continue; } /* 设置没有从excel中读到的数据 */ foreach(array_keys($fields) as $key) { if(!isset($data->$key)) { $data->$key = ''; } } $dataList[] = $data; } return $dataList; } public function setExcelFiled($count) { $letter = 'A'; for($i = 1; $i <= $count; $i++) $letter++; return $letter; } /** * 将一个对象写入到文件 * * @param $data : 要写入到excel文件的数据 * kind ：页签名称 * fields : 标题行，输入的文件要包含的字段 * rows ：对象数组，每一个数据，这些数据会通过fields过滤，只保留fields的内容（和excel2array的返回值格式一致） * fileName : 要保存的文件名 * @param $fileType : 输入文件类型，包括xls和xlsx两种类型 * @param $savePath : 文件路径 * * @access public * * @return 对象的array，每行数据为一个对象，array的大小为行数（不包含标题） * 如果输入为空，则可能是由于参数不对或者excel文件无法读取 */ public function export2excel($data, $savePath = '') { $this->phpExcel = new phpExcel(); $this->rawExcelData = $data; $this->fields = $this->rawExcelData->fields; $this->rows = $this->rawExcelData->rows; $this->fieldsKey = array_keys($this->fields); if(!$this->rawExcelData->fileName) $this->rawExcelData->fileName = $this->rawExcelData->kind; $this->excelKey = array(); for($i = 0; $i < count($this->fieldsKey); $i++) $this->excelKey[$this->fieldsKey[$i]] = $this->setExcelFiled($i); /* Set file base property */ $excelProps = $this->phpExcel->getProperties(); $excelProps->setCreator('ricky'); $excelProps->setLastModifiedBy('ricky'); $excelProps->setTitle('Office XLS Document'); $excelProps->setSubject('Office XLS Document'); $excelProps->setDescription('Document generated by PHPExcel.'); $excelProps->setKeywords('office excel PHPExcel'); $excelProps->setCategory('Result file'); /* 处理第一个页签 */ $this->phpExcel->setActiveSheetIndex(0); $sheetTitle = $this->rawExcelData->kind; $excelSheet = $this->phpExcel->getActiveSheet(); /* 设置页签名称 */ if($sheetTitle) $excelSheet->setTitle($sheetTitle); foreach($this->fields as $key => $field) $excelSheet->setCellValueExplicit($this->excelKey[$key] . '1', $field, PHPExcel_Cell_DataType::TYPE_STRING); $i = 1; foreach($this->rows as $num => $row) { $i++; foreach($row as $key => $value) { if(isset($this->excelKey[$key])) { $excelSheet->setCellValueExplicit($this->excelKey[$key] . $i, $value, PHPExcel_Cell_DataType::TYPE_STRING); } } } /* urlencode the filename for ie. */ $fileName = $this->rawExcelData->fileName; if(strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false || strpos($_SERVER['HTTP_USER_AGENT'], 'Trident') !== false) $fileName = urlencode($fileName); $excelWriter = PHPExcel_IOFactory::createWriter($this->phpExcel, 'Excel5'); $excelWriter->setPreCalculateFormulas(false); if($savePath == '') { header('Content-Type: application/vnd.ms-excel'); header("Content-Disposition: attachment;filename=\"{$fileName}.xls\""); header('Cache-Control: max-age=0'); $excelWriter->save('php://output'); } else { $excelWriter->save($savePath); } }}
测试代码中完成了excel文件的上传和下载：从本客户端择一个excel文件导入，然后完成解析后，再下载到客户端。
HTML代码很简单，没有css、js，只有一个file空间和一个提交按钮。如下所示：
"; print_r($var); echo "";}include_once 'parseexcel.class.php';/* 处理上传的文件 */if ($_FILES["file"]["error"] > 0){ echo "Error: " . $_FILES["file"]["error"] . "
"; exit;}move_uploaded_file($_FILES["file"]["tmp_name"], $_FILES["file"]["name"]);/** * excel格式: * * 姓名 | 性别 * ----------------- * ricky | 男 * xxxxx | xxx *//* 定义要读取的列，数组的值需要和excel的每一行的标题一致或子集 */$fileds = array( 'name' => '姓名', 'sex' => '性别',);$parse = new parseExcel();/* 从上传的文件中解析出数据 */$rows = $parse->excel2array($_FILES["file"]["name"], $fileds);/* 注意: 测试导入的时候，打开这个注释行，测试下载的时候需要关闭该注释行 *///output($rows);exit;/* 将数据原封不动在写入一个新的文件，供用户下载 */$data = new stdClass();/* excel的文件名 */$data->fileName = 'ceshi';/* 页签的名字 */$data->kind = 'ceshi';/* excel的标题 */$data->fields = $fileds;/* 要写入的数据 */$data->rows = $rows;$parse->export2excel($data);
