Question

So for example I have this code:

class Object{
    public $tedi;
    public $bear;
    ...some other code ...
}

Now as you can see there are public variables inside this class. What I would like to do is to make these variables in a dynamic way, with a function something like:

private function create_object_vars(){

   // The Array what contains the variables
   $vars = array("tedi", "bear");

   foreach($vars as $var){
      // Push the variables to the Object as Public
      public $this->$var;
   }
}

So how should I create public variables in a dynamic way?

Answer 1

Yes, you can do this.

You’re pretty much correct – this should do it:

private function create_object_vars(){

   // The Array of names of variables we want to create
   $vars = array("tedi", "bear");

   foreach($vars as $var){
      // Push the variables to the Object as Public
      $this->$var = "value to store";
   }
}

Note that this makes use of variable variable naming, which can do some crazy and dangerous things!

As per the comments, members created like this will be public – I’m sure there’s a way of creating protected/private variables, but it’s probably not simple (eg you could do it via the C Zend API in an extension).
