Using varibles in varibles. How do I do it?

[john278]

How do I put to variables together to make one sort of thing.



For example; I have

$dbname = "games";

$ied = "1";

echo "$dbname"."$ied"; 

I want them joined so that I end up getting: $games1 and I can then use that as a variable if you get what I mean.

[clamcrusher]

echo ${$dbname.$ied};

btw- most of the time an array is a much better solution than using variable variables. code that uses variable variables can become very difficult to read and debug. i generally would not recomend using them.

is this what you're after:

$lname = "smith";
$fname = "john";
$fullname = $fname . " " . $lname;
echo $fullname;

the . is the concatenator

It doesn't seem to be working for what I want.

[fumbler]

are you getting an error message or is the display incorrect?

[john278]

Thanks,

I have it working now.

I had to use the following
echo ${dbname.$ied};

Instead of using echo ${$dbname.$ied};

works for me, unless what you asked for was not what you really meant.

$dbname = "games";
$ied = "1";

$games1 = 'foo';

echo ${$dbname.$ied};

that seems a complex way of writing it.

$game = $dbname . $ied;
echo $game;

Yeah, I did make a little mistake. $dbname should be dbname.

works for me, unless what you asked for was not what you really meant.

$dbname = "games";
$ied = "1";

$games1 = 'foo';

echo ${$dbname.$ied};
