Name a $

[riespies]

I can't resolve this problem.
$i=$i+1;

Now $i gives a number.
I like to make a $ out of this nummer.

I thought something like

$.''$i" = 123;

How can help me?

Thanks

Variable names cannot begin with a number. You could precede the number with a string like so ...

$i=0;
$i++; //$i is now 1
${'var'.$i}='somevar'; //$var1 now contains 'somevar'

Actually...

$var = 1;
${$var} = "foo";
echo $$var;

Won't work because variables can't begin with numbers :p

Try it 😉

You will pay:glare:

No, but seriously, it's strange because if you try to then access that variable with it's static name (ie $0) you get a parse error. So the variable is only accessable dynamicaly as a variable variable, odd. In my defence I don't use variable variables, I prefer to use arrays.

Bwahahaha 😃

Variable variables have their place, I've never found much of a use for them though.
