用于将批量产品从excel上传到数据库的PHP代码

Question

我想将产品详细信息从excel（xls，xlsx）上传到我的数据库，我正在使用PHPExcel库。以下是我的代码。代码中没有错误，但仍显示查询失败，数据未存储在数据库中。可能是什么原因，请建议。如果我在哪里错了，请引导我。

这是我的代码：

<?php
error_reporting(E_ALL); 
ini_set('display_errors',1);

$host="localhost"; // Host
$username="root"; // Mysql username
$password="12345"; // Mysql password
$db_name="db_varietyhaat"; // DB name
$tbl_name="products"; // Table name

// Connect to server and select database.
$link=mysqli_connect("$host", "$username", "$password", "$db_name")or die("cannot connect");


//include the following 2 files
require_once 'PHPExcel/Classes/PHPExcel.php';
require_once 'PHPExcel/Classes/PHPExcel/IOFactory.php';

//Values
$path = "sample.xls"; //Excel File

//Reading Excel File

$objPHPExcel = PHPExcel_IOFactory::load($path);

foreach ($objPHPExcel->getWorksheetIterator() as $worksheet){
     $worksheetTitle = $worksheet->getTitle();
     $highestRow = $worksheet->getHighestRow(); // e.g. 10 For all rows
     $highestColumn = $worksheet->getHighestColumn(); // e.g 'F'
     $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
}

//Calculationg Columns
$nrColumns = ord($highestColumn) - 64;

//Displaying Sheet Details

echo "File name: " . $path;
echo '<br>';
echo "Sheet name: " . $worksheetTitle;
echo '<br>';
echo "No. of Columns: " . $nrColumns;
echo '<br>';
echo "No. of Rows: " . $highestRow;

//Inserting datas into db
$i=1;
$j=0;
for ($row = 2; $row <= $highestRow; ++ $row) {
$val=array();
for ($col = 0; $col < $highestColumnIndex; ++ $col) {
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val[] = $cell->getValue();
}
