Remove comma from number format without removing decimal point in PHP

Question

I have this code to give $value a number format:

    $value=1000000.00;

    number_format($value,2);

    echo str_replace(",", "", $value)

But when I try to replace the comma, the decimals get removed. I want to print $value as it originally was: 1000000.00. How can I do that?

you can tell [number_format](http://php.net/manual/en/function.number-format.php) what it should use as decimal-seperator! No need for the str_replace — Jeff, Mar 14 '19 at 22:49

@Quasimodo'sclone yes and no. the real issue here was the failure to assign the output of `number_format`. — Nick, Mar 14 '19 at 22:56
@Nick the question is how to properly achieve the intended result, the duplicate actually answers this. — Pinke Helga, Mar 14 '19 at 22:58

You have to assign the output of number_format to the variable:

$value=1000000.00;
$value = number_format($value,2);
echo str_replace(",", "", $value);

Output:

1000000.00

You can also simply tell number_format not to use a thousands separator:

$value = number_format($value,2,'.','');
echo $value;

Output:

1000000.00

You can tell number_format what it should use as decimal-point and thousands-seperator! No need for the str_replace:

$value = 1000000.00;
echo number_format($value, 2, ".", "");
// output:
// 1000000.00
