伙计们，我该如何创建验证，以便在导入csv文件时不会给我一个错误偏移（故意减少了csv文件列） 我收到了代码https://www.webslesson.info/2016/10/import-csv-file-data-into-mysql-database-using-php-ajax.html
这是index.php中的代码
<?php
$connect = mysqli_connect("localhost", "root", "", "db");
$query = "SELECT * FROM tbl_employee ORDER BY id desc";
$result = mysqli_query($connect, $query);
?>

这里是import.php

fgetcsv($file_data);
while($row = fgetcsv($file_data))
{

$query = "

VALUES ('$id','$name', '$address', '$gender', '$designation', '$age')

mysqli_query($connect, $query);
}
$select = "SELECT * FROM tbl_employee ORDER BY id DESC";
$result = mysqli_query($connect, $select);
$output .= '

';
}
$output .= '</table>';
echo $output;
}
else
{
echo 'Error1';
}
}
else
{
echo "Error2";
}
?>
我放置了所有代码，以便每个人都可以尝试。
感谢您的回答
