php math function
<p>Is there any alternative built in function to do the same job of the follow:</p>

<pre><code>$price = round($price,-(strlen(ceil($price))-2));
</code></pre>

<p>for example:</p>

<pre><code>$price = 1485;
echo $price = round($price,-(strlen(ceil($price))-2));//output 1500

$price = 148;
echo $price = round($price,-(strlen(ceil($price))-2));//output 150
</code></pre>
