    I need to echo a string of variables and depending on the input one may be empty. I have for example, $row['add_1'] = 15 north st $row['add_2'] = Apt 2 $row['city'] = Macon $row['state'] = GA echo $row['add_1'] . ", " . $row['add_2'] . ", " . $row['city'] . ", " . $row['state'] this will output 15 north st, Apt 2, Macon, GA. My problem occurs when $row['add_2'] is empty. the output looks like this. 15 north st, , Macon, GA How do I get rid of the extra comma if the variable is empty?
