php - 使用php在mysql中加载csv文件时出错

Question

有人可以帮我解决由于某种原因我收到错误并且无法弄清楚为什么吗!!!!我有大约 45 列，我只需要使用表中的 1,2,3,4,7,8，所以我无法加载所有内容。

    <? 
        $con=mysqli_connect("localhost","*******","*****","******");
// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
        //get the csv file
    $file = "tickets/feed/rtc.csv";
    $handle = fopen($file,"r");
    $count=0;
    $sid="32837459823";
    //loop through the csv file and insert into database
    do {
        if ($data[0]) {
            mysqli_query($con,"INSERT INTO carlist (id, stknum, vin, vt, stat, other, store_id) VALUES
                (
                    '".$count++."',
                    '".addslashes($data[7])."',
                    '".addslashes($data[8])."',
                    '".addslashes($data[2].$data[3].$data[4])."',
                    '".addslashes($data[1])."',
                    '".addslashes("0")."',
                    '".addslashes($sid)."'
                )
            ");
        }
    } while ($data = fgetcsv($handle,1000,",","'"));
    //
        ?>

这是我遇到的错误

看起来 $data 直到你点击才被定义

while ($data = fgetcsv($handle,1000,",","'"));

因此，当您尝试访问该行之前的 $data 时，您会收到错误，因为该变量不存在。
