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

I use the following code:

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

    return $result;
}
