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
