__A lot of websites are victim of outdated copyright notices, 2008, 2009 even 2000.__

This function is designed to combat this annoyance, resulting in proper copyright notices. With **valid years**, and also valid **Typography**, separating the dates with an **En dash** and using **character entities**.

Using this function in your footer will create an output string similar as:
*****
<code>2008–2011 © </code> for $startYear = 2008
*****
<code>2011 © </code> if the $startYear is equal(or bigger) compared to the current year, note that if an invalid date(higher) is passed as the argument the function will still return the current year
*****
<code>Our company 2011 © </code> for $startYear = "Our company" **(not advised)**
*****
<code>2009–2011 © Our company</code> for $startYear = 2009 and $txt = "Our company" **(advised)**
