Answer 1

I was struggling with that as well, I had this :

$user  =  array('a'=>'alber', 'b'=>'brad'...);

$array_name = 'user';

and I was wondering how to get into albert.

at first I tried

$value_for_a = $$array_name['a']; // this dosen't work 

then

eval('return $'.$array_name['a'].';'); // this dosen't work, maybe the hoster block eval which is very common

then finally I tried the stupid thing:

$array_temp=$$array_name;
$value_for_a = $array_temp['a'];

and this just worked Perfect! wisdom, do it simple do it stupid.

I hope this answers your question
