hi simple question -

How do I access an attribute of an object by name, if i compute the name at runtime?

Ie. i loop over keys and want to get each value of the attributes "field_".$key

In python there is getattribute(myobject, attrname)

It works, of course, with eval("$val=$myobject->".$myattr.";"); but IMO this is ugly!!

TIA florian
