php - 创建 CSV 上传到 Mysql

Question

我在 MYSQL 中有一个表，我希望我的客户可以在其中上传 CSV 文件。默认情况下，我希望它添加不存在的信息，并在存在信息时自动更新它。

这些是我的专栏:

id  customer_name   customer_name_letterhead    customer_notes  systype status  signaltype  verification    address postcode    telephone   mobile  mobiletwo   email   mainarea    installation    Contract    expiration  SPA nservice    maintenance monitoring  MS  certdate

我已经知道我需要一个 excel 文档，在行的标题中包含所有这些内容。例如 A1-V1 有那些 header 。

编辑: 我做了这个:

<?PHP    if(isset($_POST['SUBMIT']))
    {
         $fname = $_FILES['sel_file']['name'];

         $chk_ext = explode(".",$fname);

         if(strtolower($chk_ext[1]) == "csv")
         {

             $filename = $_FILES['sel_file']['tmp_name'];
             $handle = fopen($filename, "r");

             while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
             {
                $sql = "INSERT into Customers(id,customer_name,customer_name_letterhead,customer_notes,systype,status,signaltype,verification,address,postcode,telephone,mobile,mobiletwo,email,mainarea    installation,Contract,expiration,SPA,nservice,maintenance,monitoring,MS,certdate) values('$data[0]','$data[1]','$data[2]''$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]','$data[10]','$data[11]','$data[12]','$data[13]','$data[14]','$data[15]','$data[16]','$data[17]','$data[18]','$data[19]','$data[20]','$data[21]','$data[22]','$data[23]','$data[24]')";
                mysql_query($sql) or die(mysql_error());
             }

             fclose($handle);
             echo "Successfully Imported";
         }
         else
         {
             echo "Invalid File";
         }   
    }?>
<form action='<?php echo $_SERVER["PHP_SELF"];?>' method='post'>

    Import File : <input type="file" name="sel_file" id="sel_file">
    <input type='submit' name='submit' value='submit'>

</form>

点击提交后，没有任何反应。

我最终在 YouTube 上搜索了一段真正有帮助的视频。它最终给了我这个:

<?PHP   

if(isset($_POST['submit'])) 
{ 
    $file = $_FILES['file']['tmp_name']; 

    $handle = fopen($file,"r"); 

    while(($fileop = fgetcsv($handle,1000, ",")) !== false) 
    { 

    $customer_name             = $fileop[0]; 
    $customer_name_letterhead     = $fileop[1];
