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

Hmmm... will this work?

function get_string_a() {
global $string_b;
return "stuff $string_b and more stuff";
}

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';
} else if (condition3)
{
$string_b = 'bar';
} else
{
$string_b = 'other';
}

$string_a = "stuff $string_b and more stuff";

The reason for this is the variable substition occurs *at the time of
assignment* - not later.

Another way, if it's not easy to have your string_b setting
conditionals all in a row like that (or if this needs to be done
elsewhere in code, as well), would be:

function assignStrA($subStr)
{
$retVal = "stuff $subStr and more stuff";
return $retVal;
}

if (cond1)
{
$string_a = assignStrA('foo');
} else if (cond2)
{
$string_a = assignStrA('bar');
} else
{
$string_a = assignStrA('other');
}

O.K. that looks good, I can put in a target string to replace
instead of the variable.
Thanks for the suggestion;
