problem with variables

[Porl123]

How would I output the value of a variable, getting the name from the value of another variable? For example:

 

$var1 = 'var2';$var2 = 'output';

 

 

I want it to return 'output', which I'd imagine would work through entering something along lines of $$var1;

Does anyone know what I mean?

Yep,

a variable variable, not much of a question as you also posted the answer 

 

Example

 

 

$var1 = 'var2';$var2 = 'output';echo $$var1;

Ah yeah, I already tried that and it didn't work. I've just realised that another part of my script near the top was killing the page. :x Thanks!

You will find that in almost every case, using an array will result in simpler code. It will be faster too, because setting or referencing a variable using a variable variable is three times slower than using an array variable directly.
