Hey friends, these are the answers for the above mentioned questions.

I'm writing these answers from my experience and from searching/ studying on internet.

1. stored procedures and triggers

    stored procedures are procedures kept in database, which performs a predefined task. keeping procedures in             database instead of in scripts improves performance and also enables us to hide our business logic. But do remember, keeping un-neccessary and so many stored procedures will increase burden on database server and may affect performance of database. Triggers are also same but, one difference between them is that, triggers are called automatically on some database event, while we've to call stored procedures externally, whenever required.

2. Constraints

    Constraints are put on the records in database. constraints put some compulsions on data to be operated on. for example, foreign_key constraints.

3. difference between echo and print

   echo do not returns anything while print returns true/false on success/failure

4. difference between echo and print_r

    echo can't print arrays while print_r can.

5.Methods for retrieving data from database    There are many methods to retrieve data from database

mysql_fetch_object()

mysql_fetch_array()

mysql_fetch_assoc()

6. can we define function in function

    In php we can not define function in function

7.Syntax of creating class in php

    class myclass{

       function __construc(){

        }

       // other functions

    }

8. ???????? don't know Please answer if anybody know

9. No. of functions you have created in your past experiences

       Your personal question. answer carefully, so that you can explain which functions you have created.( even if you have created more, and forgotten)

10. What is the use of COMMIT in mysql queries

    Commit is part of the transaction, commit, rollback method in database

    if you starts a transaction in mysql using transaction begin then after performing operations of this transaction, you can either commit to these changes permanently or can rollback to the previous state.

so commit commits all the changes made in transaction in database permanently.
