PHP与Excel 笔记

一:   PHP将数据导出Excel表中（投机型）

二: PHPExcel: Github上可以下载此插件包,用法如下:

前端:

//上传阅卷员Excel文件
$("#upload_member").click(function (e) {
    e.preventDefault();
    var members_form = document.getElementById("members_form");
    var formData = new FormData(members_form);
    $.ajax({
        url: "/marking_manage/ajax_upload_members",
        method: "post",
        data: formData,
        dataType: "JSON",
        success: function (data) {
　　　　　　//这里显示php脚本读取excel文件处理后返回的值
        },
//jquery使用FormData时必须设置下面两项,否则不会成功
        processData: false,  // 不处理数据
        contentType: false   // 不设置内容类型
    })
});

//下载导入阅卷员模板
$("#download_excel").click(function (e) {
    self.location.href = "/marking_manage/ajax_download_members"
});

后端:

public function ajax_upload_members()
    {
        require_once(APPPATH . 'libraries/PHPExcel.php');
        require_once(APPPATH . 'libraries/PHPExcel/IOFactory.php');

        date_default_timezone_set("PRC");
        $file = $_FILES;
        $fileName = $file['members']["tmp_name"];
        $inputFileType = PHPExcel_IOFactory::identify($fileName);
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcel = $objReader->load($fileName);

        // 确定要读取的sheet
        $sheet = $objPHPExcel->getSheet(0);
        $highestRow = $sheet->getHighestRow();

        //读取帐号
        $accounts = array();//保存文件中的所有帐号,实际就是A列中的所有以t开头的帐号
        for ($row = 1; $row <= $highestRow; $row++) {
            $rowData = $sheet->rangeToArray('A' . $row . ':' . "A" . $row);
            $account = strtolower($rowData[0][0]);
            if (preg_match("/^t\d+/", $account)) {
                $accounts[] = $account;
            }
        }

        $accounts = array_unique($accounts);
        //过滤帐号并返回
        $this->load->model("school_admin_model");
        $retval = array();//返回值
        foreach ($accounts as $account) {
            $teacher_info = $this->school_admin_model->get_admin_by_where(array("account"=>$account));
//            $retval[$teacher_info["school_id"]][] = array("account"=>$teacher_info["account"], "teacher_name"=>$teacher_info['teacher_name']);
            $retval[$teacher_info["school_id"]][] = $teacher_info["id"];
        }
        dexit($retval);
    }

    //下载阅卷员模板
    public function ajax_download_members()
    {
        require_once(APPPATH . 'libraries/PHPExcel.php');
        require_once(APPPATH . 'libraries/PHPExcel/IOFactory.php');

        date_default_timezone_set("PRC");

        $objPHPExcel = new PHPExcel();

        $objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', '帐号')
            ->setCellValue('B1', '姓名')
            ->setCellValue('C1', '学校');

        // 设置第一个sheet为工作的sheet
        $objPHPExcel->setActiveSheetIndex(0);

        // 保存Excel 2007格式文件
        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');//如果第二个参数是"Excel5"则生成2003版本的excel文件
        browser_export('xxx','browser_excel07.xls');//输出到浏览器
        $objWriter->save('php://output');

    }

function browser_export($type, $filename)
{
    if ($type == "Excel5") {
        header('Content-Type: application/vnd.ms-excel');//告诉浏览器将要输出excel03文件
    } else {
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');//告诉浏览器数据excel07文件
    }
    header('Content-Disposition: attachment;filename="' . $filename . '"');//告诉浏览器将输出文件的名称
    header('Cache-Control: max-age=0');//禁止缓存
}
