Trailing zeroes in PHP

Question

I have a value $rating that is between 0.00 and 10.00.

I need to add trailing zeroes to numbers like 3.70 (which is 3.7) and 5.00 (which is 5). Do I need some kind of if statement too to check what value $rating is and then do some kind of str_pad? I'm not sure what to do.

See the number_format function

echo number_format(5, 2);    // returns 5.00
echo number_format(5.2, 2);  // returns 5.20
echo number_format(5.24, 2); // returns 5.24

Try number_format, something like this:

number_format((float)$yourNumber, 2, '.', '');

Damn, I meant trailing zeroes. – frosty May 07 '15 at 06:58
But you see question what he asked, he want 5.7 to become 5.70 etc. This is what it will do. – chandresh_cool May 07 '15 at 06:58
Edited, apologise for that. – frosty May 07 '15 at 07:00
