How to get not so many digits in PHP

Question

<?php echo (($priceInt[0]-$specialInt[0])/$priceInt[0])*100 ?>

For every price this gives me something like 11,111111111 or 3,3433333333 How can i limit it so i will get only 11 or 3 ? Without anything after " , ".

Answer 1

Take a look at http://php.net/manual/fr/function.number-format.php

Use it like this :

echo number_format((($priceInt[0]-$specialInt[0])/$priceInt[0])*100, 0, '', '');

If you just need the integer part just use :

echo intval((($priceInt[0]-$specialInt[0])/$priceInt[0])*100);

Answer 2

You can use sprintf() like below:

echo sprintf("%d",'3,3433333333'); //output : 3

or

echo sprintf("%d",'11,111111111'); //output : 11

In your case:

echo sprintf("%d",((($priceInt[0]-$specialInt[0])/$priceInt[0])*100));
