php - 使用 php 将 xlsx 文件上传到 mysql 时出现一个额外的字符显示所有值的问题

Question

我正在尝试上传 xlsx 文件。使用 php 和 mysql .. 但我在数据库中的一个值之后有一个额外的符号 .. 就像上传后的值是 ETI5465 它变成 ETI5465

if($_POST['action']=="addFile"){
$fname = $_FILES['sel_file']['name'];
        $path_info=pathinfo($fname);
        $ext=$path_info['extension'];




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

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

        require 'simplexlsx.class.php'; 


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


            $xlsx = new SimpleXLSX($filename);

            list($cols, $rows) = $xlsx->dimension();


            foreach($xlsx->rows() as $k => $data) { // LOOP THROUGH EXCEL WORKSHEET
                if($k >'7'){

                    if($_POST['upload']=="excel1" &&  $cols<>'10')
                    {


                    $newdate=date('m/d/Y H:i:s A',$xlsx->unixstamp($data[4]));

问题是由于文件的编码和数据库表使用的字符集引起的。例如，如果数据库表使用的字符集是 utf8_general_ci 并且从中读取数据的文件在连接到数据库后立即以 UTF-8 编码(因为它可能是您的文件)，您必须执行命令 SQL设置正确的字符集，在这种情况下:

SET CHARACTER SET utf8
