How do I convert output of number_format back to numbers in PHP?

Question

PHP can\'t recognize 1,200.00(generated by number_format) but only 1200.00,

What\'s the general solution for this problem?

Answer 1

You can use filter_var. e.g.

$num = '1,200,998';
$real_integer = filter_var($num, FILTER_SANITIZE_NUMBER_INT);
echo $real_integer;

will output:

1200998

Answer 2

In this case you can, use PHP round method like: round (12.000000, 2);

Answer 3

You could do $num = (float) str_replace(',', '', $num); Basically, just get rid of the commas, and then cast it as a numeric type (float or int).

Answer 4

I use the following code:

function remove_non_numerics($str)
{ 
    $temp       = trim($str);
    $result  = "";
    $pattern    = '/[^0-9]*/';
    $result     = preg_replace($pattern, '', $temp);

    return $result;
}

Answer 5

The better way is to use the options in number_format function itself. The format is

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

I.e. if you don't need the ',' in the formatted string make, it is like

$num=23.33333
echo number_format($num,2,'.','');

If you need that as float then typecast the same to float

$floatnum= (float) number_format($num,2,'.','');

Answer 6

use "[^0-9.]+" regex.

$formattedVal = '$9,99,999.99';
$unformattedVal = (float)preg_replace("/[^0-9.]+/", "", $formattedVal);
var_dump($unformattedVal);

worked for me.
