Please try following:

$count = count($_SESSION['product_name']);
echo $count;

for ($x = 0; $x <= $count; $x++)
{
}

Store in some variable $y

$y = count($_SESSION['product_name']);
for ($x = 0; $x <= $y; $x++) {
    if($_SESSION['product_name'][$x]!==""){
        echo "<div class=\"c_hold\">";
        echo "<div>".@$_SESSION['product_name'][$x]."</div>";
        echo "<div>".@$_SESSION['product_price'][$x]."Rs". "</div>";
        echo "</div>";
    }
}

Instead of storing in variable, you can also do:

for ($x = 0; $x <= count($_SESSION['product_name']); $x++) {
    if($_SESSION['product_name'][$x]!==""){
        echo "<div class=\"c_hold\">";
        echo "<div>".@$_SESSION['product_name'][$x]."</div>";
        echo "<div>".@$_SESSION['product_price'][$x]."Rs". "</div>";
        echo "</div>";
    }
}
