highlight less than one week away

[wxdqz]

I pull many rows from a MySQL table that all have dates entered in the XXXX-XX-XX format.

I then dump the entire list (sorted by date) into an HTML table via PHP.

how can I code it so that all dates that are less than one week from now are bold?

i.e. if (date<today+7) then echo "<B>"

thanks much!
