Percentages in PHP

Wanderer · May 2007

First of all let me say that, as a student in elementary school I had problems with mathematics.

Secondly, I know very little PHP and what I do know is hacked from other sources.

The problem...
I have 130 people visit my site.
65 of them have made comments.

Now even I know that's 50% of them, but what equation in PHP would I use to work it out?

(65/130) * 100

Thanks mate, the formula wasn't the problem, it was the syntax, structure and the rounding of the decimals.
In case anyone else is interested...

<?php
$visitors = 130;
$commentors = 65;
echo 'Visitors: '.$visitors;
echo'<br>';
echo 'Commenters: '.$commentors;
echo'<br>';
$percy = round(($commentors/$visitors)*100, 0);
echo $percy.'% of visitors have made comments'; 
?>
