How to adjusting string length

I am trying to limit the characters of a string. Additionally, if the string is less than the required characters, I want to add padding to it.

function create_string($string, $length) {
    $str_len = strlen($string);
    if($str_len > $length) {
        //if string is greater than max length, then strip it
        $str = substr($string, 0, $length);
    } else {
        //if string is less than the required length, pad it with what it needs to be the length
        $remaining = $length-$str_len;
        $str = str_pad($string, $remaining);
    }

    return $str;
}

My input is

"Nik's Auto Salon"

which is 16 characters. The second parameter is 40.

However, This string is returned

"Nik's Auto Salon        "

which has only eight characters of padding added onto it. That doesn't seem right.

I also tried this string:

Gold Package Mobile Car Detail

With this input, it returns a string with NO padding added onto it. When that phrase is shorter than the required 45 length I put in the second parameter place.

How can I make this function work according to my specifications?

str_pad doesn't add spaces equal to its second parameter, it pads the string TO the length given in the second parameter. This isn't very clear even in the documentation.

Try this instead (and take out the line where you calculate $remaining):

$str = str_pad($string, $length);
