[How do I concatenate string with variable that is empty.]

Thanks Rifts,

 

I used your method.  I knew that method was possible but I was hoping to avoid all the extra code.  I was looking for something that worked like the trim function in access.  This works though.

 

Thanks

[How do I concatenate string with variable that is empty.]

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?
