Question

Is there a way with PHP to show 2 (or x) decimal places, but not show the .00 if whole number?

I’ve looked at number_format, but it doesn’t look like it accommodates this exactly.. though I would like the commas every 3 non-decimal places

34.00  => 34
34.7   => 34.70
12424.9=> 12,424.90

My numbers are stored as floats w/ 2 decimal places in the database so I don’t necessarily need that

What you could do is check if it’s a whole number first, by rounding it using floor() and checking whether that’s equal to the full decimal version.

echo (floor($cost) == $cost) ? floor($cost) : number_format($cost, 2, '.', ',');

or

if (floor($cost) == $cost) {
    echo floor($cost);
}
else {
    echo number_format($cost, 2, '.', ',');
}

Another option is to use money_format():

echo (floor($cost) == $cost) ? floor($cost) : money_format('%.2n', $cost);

or

if (floor($cost) == $cost) {
    echo floor($cost);
}
else {
    echo money_format('%.2n', $cost);
}
