$(echo $i;) = ($i +1)

Hi there,

I wonder whether it is possible to name a variable after the contents of another variable.

i.e if I have the variables
$one = "ONE";
$two = "TWO";
$three = "THREE";

if it is possible to create the variable $THREE with the value ONE. I was thinking that something like this might work

$(echo $THREE😉 = $one;

But I got an error, so it clearly does not work. Does anyone have a suggestion?

cheers, anders

I am not sure what you meant but you said "if it is possible to create the variable $THREE with the value ONE". take a look at this code. maybe this is your answer:

$one = "THREE";
$$one = "this is a test";
echo $THREE; //output is 'this is a test'

hej anders,

use the eval() function

i have not tested this call but the correct one should be something like it:

eval("\$".$THREE."=$one");

(the \$ is for the $ character within "'s)

ha det så bra!

Hehe, almost correct...

the 100% correct one would be:

<?
$one="hej anders";
$three="bajs";

eval('$'.$three."=\"$one\";");

echo $bajs;
?>
