variables

[Anon]

Hi There,

Is this possible? And howso...

$a = "abc";
$b = "def";
$abcdef = "hello";

What I am trying to do is combine $a and $b so that I can output $abcdef.

ideally echo $a$b; would output "Hello";

How can I do this?

thanks,

Hi dr

Try using variable variables syntax:

$a = "abc";
$b = "def";
$abcdef = "hello";

//output variable variable
echo ${$a.$b};

output: hello

cheers,
Tom.

As Tom pionts out, you can do it with variable variables. But it really shouldn't be necessary. Why not just use an associative array?
