Greetings listers,

A basic question I'm sure...  (I have checked PHundamentals and did some 
googling and manual searching and book skimming but haven't come up with 
the answers I'm looking for.)

I have currently been setting variable like so:
Version A:
$print_first_name = "You said your first name is 
{$_SESSION['first_name']}.";

At one time I think I had something like:
Version B:
$print_first_name = "You said your first_name is $_SESSION[first_name].";

This would yield the same result on my server, but I think version B is 
incorrect and version A is correct.  I am thinking that Version B is 
incorrect as it is missing the single quotes around the var name, even 
though it does render OK on my server, perhaps it would not in another 
environment?

Then I also had something like:
Version C:
$print_first_name = "You said your first_name is " . 
$_SESSION['first_name'] . ".";

Now I think Version C is technically correct, and the decision to use A 
or C is based on personal preference. 

Basically I'd like to establish a standard for myself and want to make 
sure I'm understanding the usage and scenario's which can arise.

Is there a better alternative method?

Comments, thoughts, suggestions?

Thanks!
