Converting DOY to wday/mm/dd/yy

[Anon]

Given the day of the year (DOY) does anyone know how to convert this number to a formatted string?

For example, today (April 7) is the 97th day of the year. I need a function that will do a conversion as:

function ConvertDOY($DOY)
{
. . .
return $full_date;
}

When called like:

$string = ConvertDOY(97);

I want $string to contain "Saturday, April 7, 2001".

Any suggestions?

Thanks in advance.
