Thanks Hari for taking a shot at an explanation. I have found some code using mysql queries inside a class, but the code does not show how it is actually implemented inside a program. The information I found is useful in writing my own scripts, but not useful in answering some of my broader questions.

Also I dont think passing an abject is not bad ........ :) 2) Is correct or proper to instantiate a new object inside the class of another object (either in a public method or inside the constructor method)?You can do this , bcoz we call the parent class like the same ......... :) Basics of Inheritence . 3) I read one author who said the results of queries to a mysql database should be their own objects. Can some one point me to some examples or explain how they have put this into practice?There is lots of manuals available in php.net Have a search for mysqli , You can see a lot there ................Hari K T http://www.harikt.com/ Add more friends to your messenger and enjoy!
