MySQL从Excel文件更新

我find了一种从Excel文件中的多个表中导出MySQL数据库的数据的方法。 这是一个以下代码的PHP页面

<?php /*******EDIT LINES 3-8*******/ $DB_Server = "localhost"; //MySQL Server $DB_Username = "*********"; //MySQL Username $DB_Password = "********"; //MySQL Password $DB_DBName = "**********"; //MySQL Database Name $filename = "exportproizvoda"; //File Name /*******YOU DO NOT NEED TO EDIT ANYTHING BELOW THIS LINE*******/ //create MySQL connection $sql = "SELECT product_description.name, product_description.product_id, product.upc, product_to_category.product_id, product_to_category.category_id FROM `product_description`, `product_to_category`, `product` where product_to_category.category_id=571 and product_description.product_id = product_to_category.product_id and product.product_id = product_to_category.product_id group by product_to_category.product_id order by product_description.name limit 0, 800"; $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to MySQL:<br>" . mysql_error() . "<br>" . mysql_errno()); //select database $Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database:<br>" . mysql_error(). "<br>" . mysql_errno()); //execute query $result = @mysql_query($sql,$Connect) or die("Couldn't execute query:<br>" . mysql_error(). "<br>" . mysql_errno()); $file_ending = "xls"; //header info for browser header("Content-Type: application/xls"); header("Content-Disposition: attachment; filename=$filename.xls"); header("Pragma: no-cache"); header("Expires: 0"); /*******Start of Formatting for Excel*******/ //define separator (defines columns in excel & tabs in word) $sep = "\t"; //tabbed character //start of printing column names as names of MySQL fields for ($i = 0; $i < mysql_num_fields($result); $i++) { echo mysql_field_name($result,$i) . "\t"; } print("\n"); //end of printing column names //start while loop to get data while($row = mysql_fetch_row($result)) { $schema_insert = ""; for($j=0; $j<mysql_num_fields($result);$j++) { if(!isset($row[$j])) $schema_insert .= "NULL".$sep; elseif ($row[$j] != "") $schema_insert .= "$row[$j]".$sep; else $schema_insert .= "".$sep; } $schema_insert = str_replace($sep."$", "", $schema_insert); $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert); $schema_insert .= "\t"; print(trim($schema_insert)); print "\n"; } ?> 

我想更改某些产品的名称或类别，并将修改后的文件导入到数据库中，然后更新产品。 有可能吗？
