join two variables to a new one

[babil]

Hi all,
a pretty straight forward example follows. Is this possible??
any help appreciated.

Thanks in advance
babil

$a_0=1;
$b=0;
$c="\$a_".$b;
echo $c; // output must be 1, not "$a_0"

Read the PHP Manual on variable variables.

$a_0 = 1;
$b = 0;
$c = ${'a_' . $b};
echo $c; // output should be 1

Still, have you considered using an array instead?

cool thanks it worked. I was not really sure if this was possible at all. I don't really need it in PHP. I need it in Actionscript, but I thought that if this is possible in PHP it should be possible in Actionscript too. I am writing a script in PHP that reads the values from a DB and parses it into Actionscript. I save the data in Arrays and then echo them as '&data_'.$i which is the format that Flash and AS understand.
This saves me a lot of time in AS and I don't have to use arrays there.
Just for the info, I just figured it out how this works with Actionscript.

many thanks
babil
