Re: [fw-general] instantiate an object with a variable name for the class

Hi Denis,

I understand what you are trying to do, unfortunely get_class(self) will not 
work if self is an extended class (as Zend_Db tables are), the only 
workaround (until 5.3 is out where will be possible to do this) is to create 
a method, this is how I do it:

create an interface

interface My_Interface
{
   public static function init();
}

then create your class

class My_Class extends Zend_Db_Table implements My_Interface
{
   ...

   public static function init()
   {
       return new self;
   }
}

then, when you need the class you must use $myClass::init() instead of new 
$myclass

Hope it helps,

Aldemar

Thank you for your response Vincent,

for now, i have no other solution than instantiate the object before 
calling my constructor and pass the Zend_Db_Table objects to it instead of 
passing strings with their names... but it's not exactly what i wanted to 
do.

cheers

    Hi all,

    sorry i forgot the subject in my previous post :

    i'm trying to implement a class to manage manytomany relationships
    in backoffice, i'd like to standardize it for reusability.
    I would like to pass to the constructor of my class the name of the
    tables involved (destination table, origin table, intersection
    table) and that it instantiate correspondings Zend_Db_Table objects.

    So now is the question : how can i instantiate an object
    (Zend_Db_Table here) with a variable classname :

    function __construct ($originTable, $destinationTable) {

       $table1 = new $originTable();
       ...

    }

    i can't find what i want on google (tried call_user_func but that's
    not it).


This sounds similar to something I've been trying to do a while ago. 
After reading a *lot* about this, I found out this was not possible 
before PHP 5.3. I'm not sure exactly where I found that, but a good 
starting point would be the comments on http://nl3.php.net/get-class .

    Thanks.

    Denis.


Best of luck,
