Question

I’m trying to send a number from a page to another on in order to save it on my database, but when I use number_format method the number is converted to 0:

<?php
    $_REQUEST["myNumber"]; // the number from the url is 25%2C8 (25,8)
    // why this returns 0? 
    number_format (urlencode($_REQUEST["myNumber"]), 2, ".", "");
?>

I thought urlencode function was useful to convert url numbers to string numbers, where’s my fault?

Answer 1

You need to use urldecode function instead of urlencode if you want to decode characters. And pass ‘,’ as decimal pointer.

So your code should looks like this:

number_format (urldecode($_REQUEST["myNumber"]), 2, ",", "");

But you need to take to account that variables in $_POST\GET\REQUEST arrays is already decoded. Perhaps, your code may be even simpler:

number_format ($_REQUEST["myNumber"], 2, ",");
