[PHP] Convert a grayscale value to a #RRGGBB hex value

Anyone know how I might convert a grayscale value, from between 0 to 100, to hex, such that 0 (black) would be returned as #00, and 100 (white) as #FF? For example... function grayscaletohex ($val) { $hex = $val ... [ a simple operation ] return $hex; } Thanks.
