PHP: Converting an url variable number to a number

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?

number_format expects a number (float, to be exact) as the first argument, and the '25,8' won't be recognized as float. You'd need to do something like:

str_replace(',','.', $_REQUEST["myNumber"]); // '25,8' --> '25.8'

to convert a single comma to a string that can be evaluated as decimal number (which can be stored in db).

Running:

print number_format('25,8', 2);

returns 25.00 which is not 25.80 (which I assume is your desired result).

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, ",");
