Can you refer to a var using a string in PHP?

Question

What I mean is can I do something like this...

$number = 1;
$varname = 'number';

Now I want to get the value of $number by using $varname so something like...

echo $($varname);

Output:

[`${$varname}`](http://php.net/manual/en/language.variables.variable.php), usually an array is a way better solution — kero, May 16 '14 at 15:32

You need to use {} instead of ():

echo ${$varname};

Or even shorter:

echo $$varname;

Which equals:

echo ${'number'};

But as kingkero pointed out: You probably want to do something like ${'number'.$index} and that is easier solved with arrays.

Don't even need that. `echo $$varname;`. – Niet the Dark Absol May 16 '14 at 15:33
Missing a $ before varname, but this worked, thanks! – clearmend May 16 '14 at 15:35
Heh thanks Niet, didn't know that was possible :) – Laoujin May 16 '14 at 15:35
