原生PHP網頁導出和導入excel文件實例

原生PHP實現的網頁導出和導入excel文件實例，包括上傳也是用的原生。還可在exportExcel方法里設置字體等表格樣式。

導出和導入表單代碼：

<p style="margin:10px 0"><a href="export.php" 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>

excel導出：

$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++; 
}  
 
$title = array('ID', '郵箱', '密碼'); //設置要導出excel的表頭 
exportExcel($list, '素材火用戶表', $title);

exportExcel方法代碼：

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'); 
}

excel導入：

$tmp = $_FILES['file']['tmp_name']; 
if (empty($tmp)) { 
    echo '請選擇要導入的Excel文件！'; 
    exit; 
} 
 
$save_path = "uploads/"; 
$filename = $save_path . date('Ymdhis') . ".xls"; //上傳后的文件保存路徑和名稱  
if (copy($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,password) values ('" . $v['B'] . "', '" . $v['C'] . "')"; 
 
            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; 
}
