原生PHP网页导出和导入excel文件实例

原生PHP实现的网页导出和导入excel文件实例，包括上传也是用的原生。还可在exportExcel方法里设置字体等表格样式。

导出和导入表单代码：

        Excel表格：

excel导出：

$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]['password'] = $row['password'];  
    $i++; 
}  

$title = array('ID', '邮箱', '密码'); //设置要导出excel的表头 
exportExcel($list, '素材火用户表', $title);

exportExcel方法代码：

function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') { 
    require_once 'PHPExcel.class.php'; 
    //若没有指定文件名则为当前时间戳 
    if (is_null($savefile)) { 
        $savefile = time(); 
    } 
    //若指字了excel表头，则把表单追加到正文内容前面去 
    if (is_array($title)) { 
        array_unshift($data, $title); 
    } 
    $objPHPExcel = new PHPExcel(); 
    //Excel内容 
    $head_num = count($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 
            $nn++; 
        } 
    } 
    //设置列头标题 
    for ($i = 0; $i < $head_num - 1; $i++) { 
        $alpha = chr(65 + $i); 
        $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应  
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setName("Candara");  //设置字体 
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setSize(12);  //设置大小 
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); //设置颜色 
        $objPHPExcel->getActiveSheet()->getStyle($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); //题目 
    $objPHPExcel->setActiveSheetIndex(0); //设置当前的sheet   
    header('Content-Type: application/vnd.ms-excel'); 
    header('Content-Disposition: attachment;filename="' . $savefile . '.xls"');//文件名称 
    header('Cache-Control: max-age=0'); 
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); //Excel5 
    $objWriter->save('php://output'); 
}

excel导入：

$tmp = $_FILES['file']['tmp_name']; 
if (empty($tmp)) { 
    echo '请选择要导入的Excel文件！'; 
    exit; 
} 

$save_path = "uploads/"; 
$filename = $save_path . date('Ymdhis') . ".xls"; //上传后的文件保存路径和名称  
if (copy($tmp, $filename)) { 
    require_once 'PHPExcel.class.php'; 
    require_once 'PHPExcel/Reader/Excel5.php'; 

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

    //获取表中的第一个工作表，如果要获取第二个，把0改为1，依次类推 
    $currentSheet = $PHPExcel->getSheet(0); 
    //获取总列数 
    $allColumn = $currentSheet->getHighestColumn(); 
    //获取总行数 
    $allRow = $currentSheet->getHighestRow(); 
    //循环获取表中的数据，$currentRow表示当前行，从哪行开始读取数据，索引值从0开始 
    for ($currentRow = 1; $currentRow <= $allRow; $currentRow++) { 
        //从哪列开始，A表示第一列 
        for ($currentColumn = 'A'; $currentColumn <= $allColumn; $currentColumn++) { 
            //数据坐标 
            $address = $currentColumn . $currentRow; 
            //读取到的数据，保存到数组$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,password) values ('" . $v['B'] . "', '" . $v['C'] . "')"; 

            mysql_query($sql); 
        } 
    } 

    $sql = "SELECT * FROM user"; 
    $result = mysql_query($sql); 
    $tip = '用户导入成功' . '，现在' . mysql_num_rows($result) . '条数据了！'; 
    echo ""; 
    exit; 
}
