variable substitution

Hello again;
I have two variables declared in the global scope of a script.
$string_a = 'stuff $string_b and more stuff';
$string_b = '';
One is a string with a reference for substitution to the other
string which is empty.
In the processing body of the script are if/if else blocks.
In these blocks I want to use $string_a  and
set $string_b  to a value
if( condition)
{ $string_b = 'by the way;';... etc
so $string_a should read:
"stuff and by the way; and more stuff"
But this substitution will not take place
in the context of the else if block. I do not
want to write $string_a in at least 5 different
if else blocks because it is about 10 lines
intended to be an e-mail message body -> !SPAM.

this script is used to process data sent from a
link in another e-mail message used to validate
and e-mail address.

Q: Is there a way to get the substitution to take
     place here? (by reference, maybe?)

Thank you in advance for info
Jeff K

Several ways to do this (and avoid globals or a str_replace call):

#1:

if (condition)
{
  $string_b = 'blah';
} else if (condition2)
{
 $string_b = 'foo';
