PHP List - Conditional Formatting -

I have a PHP date field with renewal dates "datetime".

How would I specify a style class / id in a row that was the date within 30 days of today?

For example

Mr. John Doe 31-03-2016 Mr. John Test 31-05-2016

The top row will have a class of "renewal" . There are so many distances here

  & lt ;? Php $ query = mysql_query ("Choose from * homepolicynumber with order ID") or die (mysql_error ()); Echo "& lt; Table border = '0' width = '100%' cellpadding = '10'>"; Echo "& lt; tr height = '25px' = 'center' square valign = 'head' & gt; width = '20px'>
