基于PHPExcel库的EXCEL导入导出

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 .

测试代码：

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：

Filename:

对应的后台的代码如下：

";    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);

上述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、合并单元格等没有体现在这里，大家可以参考PHPExcel的手册，下面是我摘出来的PHPExcel的常见的一些操作，供大家参考：
