showing the decimal places

when I define a number as

$number = 2.00

then echo it the number shows as 2. How can I get the two zeros to show?

This is not in any of my books but a fairly easy solution I'll bet!

the function you want is called sprintf (s for string, f for format)
summat like this:

echo sprintf('%0.2f', $number);

please consider php.net as your book too ;-)

have fun with the following:

<?php

$newLine = ($viaWeb = isset($_SERVER["HTTP_HOST"]))
? "<br />"
: "\n";

$number = 2.00;

echo $number; echo $newLine;
var_dump( $number ); if ($viaWeb) { echo $newLine; }
printf("%0.2f", $number); echo $newLine;
echo number_format( $number, 2 ); echo $newLine;
echo sprintf("%01.2f", $number); echo $newLine;
echo number_format(123456789, 2, ",", " "); echo $newLine;
