通过phpexcel将数据从excel表上传到sql

Question

我使用php Excel将一张3400行的Excel表格上传到MySQL数据库。但它只能上传3000个条目。我检查了主键列的所有重复项和所有内容。一切都好。

就在从Excel工作表中通过print_r打印数据时，它显示完整的数据3400行，但在尝试导入到SQL时，它只导入3000个条目

最高的帮助将受到高度赞赏..

include_once("config.php");

if (isset($_POST['addproduct'])) {
    //error_reporting(0);
    set_time_limit(0);  ini_set('upload_max_filesize', '100M'); 
    ini_set('memory_limit','128M');

    $con->query("UPDATE products SET STOCK='out of stock'") ; 

    function newsku($item)
    {   
        $olditem = trim($item);
        $olditem = str_split($item);
        $newsku = '' ; 
        foreach ($olditem as $a)
        {
            $newsku .= $a + 1;
