Warning: Division by zero in C:\xampp\htdocs\engine\core.php on line 629
<p>I'm new to PHP and I have an error on my website and can't figure out the right way to fix it.</p>

<p>The error:</p>

<pre><code>Warning: Division by zero
</code></pre>

<p>The code I'm using:</p>

<pre><code>public function percent($num_amount, $num_total)
{
    $count1 = $num_amount / $num_total;
    $count2 = $count1 * 100;
    $count = round($count2);

    return $count;
}
</code></pre>

<p>I know it has something to do with dividing by 0 which obviously can't.
But how do I change that and fix this error?</p>
