Answer 1

Use name quantity[] instead of quantity.By this way you can receive post data as an array. After the loop use only one submit button.
echo "<input type='number' name='quantity[]' value='1' class='form-control'/>";
Then receive it by using foreach
foreach($_POST['quantity'] as $qty)
{
echo $qty;
//Here you will receive all the quantities one by one.
}
Form the code
<?php
echo "<table class='table table-hover table-responsive table-bordered'>";
// our table heading
echo "<tr>";
echo "<th class='textAlignLeft'>Product Name</th>";
echo "<th>Price</th>";
echo "<th style='width:5em;'>Quantity</th>";
echo "<th>Image</th>";
echo "</tr>";
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
extract($row);
//creating new table row per record
echo "<tr>";
echo "<td>";
echo "<div class='product-id' style='display:none;'>{$id}</div>";
echo "<div class='product-name'>{$name}</div>";
echo "</td>";
echo "<td>$" . number_format($price, 2, '.' , ',') . "</td>";
if(isset($quantity)){
echo "<td>";
echo "<input type='text' name='quantity[]' value='{$quantity}' disabled class='form-control' />";
echo "</td>";
echo "<td>";
echo "</td>";
echo "<td>";
echo "</td>";
}else{
echo "<td>";
echo "<input type='number' name='quantity[]' value='1' class='form-control'/>";
echo "</td>";
echo "<td><img src='product-images/{$image}' width='60' height='60'</td>";
echo "<td>";
echo "</td>";
}
echo "</tr>";
}
echo "<tr><td colspan='4'>";
echo "<button class='btn btn-primary add-to-cart' type='submit'>";
echo "<span></span>Submit to cart";
echo "</button>";
echo "</td></tr>";
echo "</table>";
