change the name of a variable inside an array bracket

[jeff5656]

I am echoing a variable that is an array.  I want to change the first part of the variable but don't know how to manipulte names inside the ['brackets']

echo $row['v1_name']);?>

 

lets say I have a value called $var = v1.  How do I substitute that like this:

echo $row[$var.'_name']);?>

 

I know the above doesnt work, but thats what i want it to do :-)

Never mind - that actually works.  I didn't kow yu could combine variables inside a bracket like you can elsewhere.
