Well, according to php manual, the braces are used in the following fashions:

$$var
${$var}

I can't find {$$var} syntax, neither does it work. it throws a syntax error.

>From that, the following code works for me on an php 4.3.11 machine:

$num = count( ${$list} );
echo ${$list}[0][0];

Hope that helps.
