Eliminating space between number and currency

Question

My script for showing the discount amount or percentage is;

function DisplayDiscount($value)
    {
        if (strstr($value,'%'))
             $discount = "%".substr($value, 0, -1); //$discount = $value;
        else
            $discount = $value.SITE_CURRENCY;

        return $discount;
    }

Outcomes;

• %18.30
• 18.30 XX

I want to eliminate the space between the value and XX but I could not figure it out.
