Using number_format without changing decimal

[tencip]

Hi everyone,

So, I'm running data through an array, and having a little difficulty
in using the number_format function. You see, I'm trying to get a
comma to appear for the thousandths place, however, whenever i use the
number_format function, it also forces rounding of the decimal.

Does anyone know how I can place commas in the thousandths place
WITHOUT doing any decimal rounding? I have some datapoints with two
decimal places, some with four, and others with none. I don't want to
have the function affect any of these decimal places.

Any suggestions?

preg_replace('/0+$/','',number_for mat($number,4,' .',','))

This is a bit gruesome but it's the first thing that came to mind:

<?php
function number_format_k eep_decimals($n um)
{
if ($point = strrpos($num, '.'))
{
return number_format($ num, strlen($num) - $point - 1);
}
else
{
return number_format($ num);
}
}

$nums = array(1000.2, 2000.34, 5000.678, 9000);

foreach ($nums as $num)
{
print $num . ' -> ' .number_format_ keep_decimals($ num);
print "<br>";
}
?>
