[moka同學筆記]PHPexcel之excel導出和導入，mokaphpexcel

原案例來自http://www.sucaihuo.com/      有修改      

1.目錄結構（文件不用解釋，應該都可以看得懂，直接看代碼）

2.注意數據庫表（需要在connect.php中修改數據庫配置）

創建數據庫表

CREATE TABLE `user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(15) NOT NULL,
  `email` varchar(20) DEFAULT NULL,
  `grade` int(11) DEFAULT NULL,
  `password` varchar(32) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;

3.代碼

   視圖index.php

            <div class="demo">
                <h2 class="title"><a href="http://www.sucaihuo.com/js/140.html">教程：PHPexcel之excel導出和導入</a></h2>
                <p>class="btn">導出</a></p>
                <form action="import.php" method="post" enctype="multipart/form-data">
                    <div class="control-group">
                        <label>Excel表格：</label>
                        <input type="file"  name="file"/>
                    </div>
                    <div class="control-group">
                        <input type="submit"  value="導入" />
                    </div>
                </form>
            </div>

4.導入（import.php）

<?php

include_once('connect.php');
$tmp = $_FILES['file']['tmp_name'];
if (empty($tmp)) {
    echo '請選擇要導入的Excel文件！';
    exit;
}

$save_path = "uploads/";
$filename = $save_path . date('Ymdhis') . ".xls"; //上傳後的文件保存路徑和名稱 
if (copy($tmp, $filename)) {
    require_once 'PHPExcel.class.php';
    require_once 'PHPExcel/Reader/Excel5.php';


    $PHPReader = new PHPExcel_Reader_Excel5(); //PHPExcel_Reader_Excel2007 PHPExcel_Reader_Excel5
    //載入文件
    $PHPExcel = $PHPReader->load($filename);

    //獲取表中的第一個工作表，如果要獲取第二個，把0改為1，依次類推
    $currentSheet = $PHPExcel->getSheet(0);
    //獲取總列數
    $allColumn = $currentSheet->getHighestColumn();
    //獲取總行數
    $allRow = $currentSheet->getHighestRow();
    //循環獲取表中的數據，$currentRow表示當前行，從哪行開始讀取數據，索引值從0開始
    for ($currentRow = 1; $currentRow <= $allRow; $currentRow++) {
        //從哪列開始，A表示第一列
        for ($currentColumn = 'A'; $currentColumn <= $allColumn; $currentColumn++) {
            //數據坐標
            $address = $currentColumn . $currentRow;
            //讀取到的數據，保存到數組$arr中
            $data[$currentRow][$currentColumn] = $currentSheet->getCell($address)->getValue();
        }
    }

    $add_time = date('Y-m-d H:i:s', time());
    foreach ($data as $k => $v) {
        if ($k > 1) {
            $sql = "insert into user (username,email,password) values ('" . $v['B'] . "', '" . $v['C'] . "', '" . $v['D'] . "')";

            mysql_query($sql);
        }
    }

    $sql = "SELECT * FROM user";
    $result = mysql_query($sql);
    $tip = '用戶導入成功' . '，現在' . mysql_num_rows($result) . '條數據了！';
    echo "<script>alert('" . $tip . "');history.go(-1);</script>";
    exit;
} 

5.導出（export.php）

<?php

/**
 * PHPEXCEL生成excel文件
 * @author:素材火  http://blog.csdn.net/winter13292/article/details/8123755
 * @desc 支持任意行列數據生成excel文件，暫未添加單元格樣式和對齊
 */

include_once('connect.php');

//$list = array(
//    array('id' => '1', 'email' => "87423050@qq.com", 'password' => 'sucaihuo.com'),
//    array('id' => '2', 'email' => '41614@qq.com', 'password' => 'hjl666666'),
//    array('id' => '3', 'email' => 'zhangliao@163.com', 'password' => 'zhangqirui'),
//);
$query = mysql_query("select * from user limit 50"); 
$i =0;
$list = array();
while($row=mysql_fetch_array($query)){ 
    $list[$i]['id'] = $row['id']; 
    $list[$i]['username'] = $row['username'];
    $list[$i]['email'] = $row['email'];
    $list[$i]['password'] = $row['password'];
    $i++;
} 

$title = array('ID', '姓名','郵箱','密碼'); //設置要導出excel的表頭
exportExcel($list, '名單表', $title);

function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') {
    require_once 'PHPExcel.class.php';
    //若沒有指定文件名則為當前時間戳
    if (is_null($savefile)) {
        $savefile = time();
    }
    //若指字了excel表頭，則把表單追加到正文內容前面去
    if (is_array($title)) {
        array_unshift($data, $title);
    }
    $objPHPExcel = new PHPExcel();
    //Excel內容
    $head_num = count($data);

    foreach ($data as $k => $v) {
        $obj = $objPHPExcel->setActiveSheetIndex(0);
        $row = $k + 1; //行
        $nn = 0;

        foreach ($v as $vv) {
            $col = chr(65 + $nn); //列
            $obj->setCellValue($col . $row, $vv); //列,行,值
            $nn++;
        }
    }
    //設置列頭標題
    for ($i = 0; $i < $head_num - 1; $i++) {
        $alpha = chr(65 + $i);
        $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //單元寬度自適應 
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setName("Candara");  //設置字體
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setSize(12);  //設置大小
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); //設置顏色
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setBold(true); //加粗
    }

    $objPHPExcel->getActiveSheet()->setTitle($sheetname); //題目
    $objPHPExcel->setActiveSheetIndex(0); //設置當前的sheet  
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="' . $savefile . '.xls"');//文件名稱
    header('Cache-Control: max-age=0');
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); //Excel5
    $objWriter->save('php://output');
}
