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

[Denis Fohl]

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).

Thanks.

Denis.
