Re: [PHP] echo'ing array contents through reference variable

[Tularis]

echo ${$pdag[$n]}; // is also possible in case the [$n] is the index to pdag. Otherwise use this:
echo ${$pdag}[$n];

- Tularis

PS. This is basicly the same thing as Ernest said, but shorter...

This is ambiguous: is it "$$pdag" indexed by "[$n]", or is it "$pdag[$n]"
dereferenced? If you're using an interim variable you'll get what you need
- either use (depends on your data layout which I don't know)
    $temp = $pdag[$n];
    echo $$temp;
or
    $temp = $$pdag;
    echo $temp[$n];
