Answer 1

Try This:

$qry  = "INSERT INTO `pr`(`pur`, `empid`, `appb`, `expdate`, `appn`, `specification`, `qty`, `esp`) VALUES ";
$i = 0;
foreach($qty as $a => $b) {                   

    $qry .= "('$pur[$a]','$empid[$a]','$appb[$a]','$expdate[$a]','$appn[$a]','$specification[$a]','$qty[$a]','$esp[$a]')";
    if($i == count($qty)) {
        $qry .= ";";
    } else {
        $qry .= ",";
    }

$i++;
} 

$result = mysqli_query($mysqli, $qry);

If you have large data then use insert query once, It will increase efficiency.

Answer 2

Just make the with the field name and use implode function while inserting data.

For example:

    $data['name'] = 'abc';
    $data['description'] = 'description';
    $data['created'] = date("Y-m-d H:i:s");

Query:

     $fields = array_keys($data);
        $sql = "INSERT INTO table_name . (`" . implode('`,`', $fields) . "`) 
                VALUES('" . implode("','", $data) . "')";
