php - Accessing object variable via double dollar sign -

I am creating a square to create variables so that another php file can be easily created.

The problem is that I get $ variable_name = & gt; I'm using double dollars to make. $$ varible_real_value Style hashp and I want all the Iterator features to be square variables __Constructor defining a new variable in the scope can overwrite the variable from the files. The problematic piece of code is

  foreach ($ this-> Args AS $ this-> iterator) {$ this-> Data-> $ The-> iterator = $$ this-> Iterator; }   
 But when I call it  
  foreach ($ this-> args as $ var) {$ this-> Data-> $ Var = $$ var; }   
 The variable '$ var' will be overwritten.  
  class DataFile {private $ data = zero, $ iterator = null, $ args = null; Public function __ conversion ($ file) {requirement ($ file); Not set ($ file); $ This- & gt; Args = funny_gate_argain (); ($ This-> args) array_shift; $ This- & gt; Data = new ArrayObject (); Forex Currency ($ this-> Args AS $ this-> Iterator) {$ this-> Data-> $ The- & gt; Iterator = $$ this-> Iterator; }} Public Function __get ($ key) {Return $ this- & gt; Data-> $ Key; }}   
 example usage:  
  $ conf = new data file ('mysql.php', 'var'); $ Databasename = $ conf- & gt; Var- & gt; Database;   
 Is there any alternative solution for this,  
 thanks   
 
 
  $ this-> Data-> $ This- & gt; Iterator  is ambiguous What do you mean by  $ this- & gt; Data is the property of  whose name is  $ it-> iterator  or  iterator  property  $ this- & gt; Data-> $ This ?  
 You should clarify it:  
  $ this-> Data-> {$ This-> Iterator}   
 goes to the same  $$ it-> iterator .
