How do I combine output from a phrase with a variable...

[JJR512]

I need to have something like this:

Phrasetext Variabletext

Where "phrasetext" is the output from a phrase, and "variabletext" is the value of a variable.

I have this to start with:

$title = $vbphrase['phrasename']

But I don't know how to get the variable text after the phrase text. Is it possible to do this all in one code line, or do I need to have multiple lines, each one adding to the result of the one before it? I'd prefer to have just one line do it all, for elegance, but I'll do it the brute-force way if necessary. Either way, I'd greatly appreciate it if you could give me a specific code example to use.

This will be used in a hack I'm about to release, and I will be sure to credit assistance to whomever's example I use.

Here's another question for the same project:

Can a variable be part of a phrase name? For example, through the URL you pass $var to the script. Can $var be part of the phrase name, as in:

$title = $vbphrase['phrasename_$var'];

I've already found out it doesn't work if I try it exactly like that (the output was blank, but if I hardcoded the variable in the phrase name, like phrasename_value, it did produce an output, so I know the problem is the $var in the phrase name). But is there another way to do it?
