how do i round in php with keeping the two zeros

Question

I have this php

and the $price maybe 1.0000

i want 1.00

Answer 1

number_format is your best bet.

string number_format ( float $number , int $decimals = 0 , string $dec_point = '.' , string $thousands_sep = ',' )

Example:

<?php echo number_format(1.0000, 2, '.', ','); ?>

Answer 2

number_format works:

echo number_format($price, 2);

Answer 3

The following printf() call should work for you:

<?php printf("%.2f", $price); ?>

The documentation for this syntax is best described on the sprintf() page.
