Reverse of number in PHP not showing correct output
<p>I have made a program to reverse the number but every time <code>0</code> gets appended to the result.</p>

<pre><code>$num = 675;
$rev = 0;

while($num &gt; 0) {
$temp = $num % 10;
$rev = ($rev *  10) + $temp;
$num = (int) $num / 10;
}

echo $rev;   //result is 5760
</code></pre>
