Windows cannot access the specified device path or file. The number of clicks to download the file is backfilled.

A mysql database table named book is required. The table contains the following fields:
id Unique identifier of the downloaded file
downnum Number of clicks
first.php
{
?>



< ;/TD>

click here download



ddload.php
     include("data. inc.php");
if($incerror)
{
echo $incerror;
exit; }
if(empty($dnnum)) $dnnum = 1; else $dnnum ++;
$sql = " update book set downnum ='$dnnum' where id =$id";
mysql_query($sql); mysql_close($connect); header("location:$purl");
?>

The above introduces the backfill of the number of clicks to download files when Windows cannot access the specified device path or file, including the content of Windows cannot access the specified device path or file. I hope it will be helpful to friends who are interested in PHP tutorials.
