Combine 4 variables into one variable name!

Question

I dont think this is right...

$compname = $subformat_$subgame_$subname_$subseason;

What is the correct syntax? THanks

Answer 1

$compname = implode('_', array ($subformat,$subgame,$subname,$subseason));

or

$compname = sprintf("%s_%s_%s_%s", $subformat, $subgame, $subname, $subseason);

or

$compname = "$subformat_$subgame_$subname_$subseason";

Answer 2

grossvogel solution is correct. You may also want to know this is good:

$compname = {$subformat.'_'.$subgame.'_'.$subname.'_'.$subseason};

But what you're trying to do looks really weird... Why don't you use a four dimension array?
