這裡分2中情況：

1.字尾為xls和xlsx

2.字尾為csv

注意：字尾為csv的一次可以匯入上萬條資料，字尾為xls和xlsx的能導幾千條，csv是一個黑科技

字尾為csv的情況：

1.獲取上傳的檔名$_FILES['file']['name']

2.上傳的零時檔案$_FILES['file']['tmp_name']

3.獲取檔案的字尾名：主要用到的：explode

4.設定上傳路徑$savePath 和 給檔案建立的新的檔名(一般以時間來命名)

5.複製檔案到專案中：用到：copy($tmp_file,新的路徑.新的檔名)

6.讀取儲存的檔案：file_get_contents(新的路徑.新的檔名);

7.進行資料的替換

8.插入資料庫

9.刪除上傳的檔案

具體程式碼如下

字尾為xls和xlsx（excel）

1.需要匯入phpexcel類

    import("Org.Util.PHPExcel");

    $objPHPExcel = new \PHPExcel();

    import("Org.Util.PHPExcel.IOFactory");

    import("Org.Util.PHPExcel.Cell");

2.關於phpexcel的學習這裡就不介紹了（可以自己查文件）

3.具體程式碼如下

程式碼如下：

    public function order_import()
    {
        header('content-type:text/html;charset=utf-8');
//        if(!empty($this->now_id)){
            set_time_limit(0);
            if (!empty ($_FILES ['file'] ['name'])) {
                //上傳的檔名
                $old_name = $_FILES 
 
['file'] ['name'];
                //上傳的零時檔案
                $tmp_file = $_FILES ['file'] ['tmp_name'];
                //以.將檔名分割成陣列
                $file_types = explode(".", $old_name);
                //獲取檔名的字尾
                $file_type = $file_types [count($file_types) - 1];   //string(3) "xls"

                /*判別是不是.xls檔案，判別是不是excel檔案*/
                if (strtolower($file_type) != "xls" && strtolower($file_type) != "xlsx") {

                    if (strtolower($file_type) != "csv") {
