[Resolved] variable naming

I want to create a variable whose name is the short string of another variable.

For example:
$a = 'foo';

$a will change with each line of a file it reads. I want my script to make $foo;

And then later in the file, $a might be equal to 'bar' at which point I want $bar to be created as a new variable.

How do I do this?

I'm not sure I quite follow but try something like this:

$a = 'foo';

$$a = 'whatever';

$a = 'bar';

$$a = 'something';

// Now you have three variabls.
// $a = bar
// $foo = whatever
// $bar = something

Yes, thankyou both for the responses. Variables variables is exactly what I'm looking for🙂

Thanks!
