How to format a number after division to two decimal places?

I am probably completely missing this but i am wanting this to take it to 2 decimal places not round the whole thing..

$size = ceil($d['size']/1024/1024);

so with out the ceil
I get this number
1.24835586548Mb

and with the ceil i get 2mb

i want it to look like this
1.25

i want it to go 2 decimal places

I am thinking you are using PHP. I would use the PHP round function:

http://php.net/manual/en/function.round.php

So you would do something like:



The second argument is the precision that you want.

thanks that worked. i guess i didn't scroll down far enough and had seen the round feature..

another question for some reason i keep getting

Warning: Cannot modify header information - headers already sent by (output started at /home/ppeeps/ekazer.com/pages/Files/index.php:4) in /home/ppeeps/ekazer.com/pages/Files/index.php on line 133


but that line is
header("Location: ".$session->referrer);

the $session->referrrer does work and dont have any issues. but it does it rather i use that or i use
header("Location: index.php");

any ideas?

You can only use header() before PHP produces ANY output to the client, e.g. echo() statements or the like.

so what is recommended?

Find wherever in your code that you're producing output before the call to header(), and remove it.
