I have 2 classes, Base.class.php and MyClass.class.php. MyClass extends Base. Base has a var $link which is initialised as a mysql database connection when the constructor is called.
Base also has a function destroy() which closes the link.

Each page uses $myClass = new MyClass(); thereby initialising $link in Base. At the end of each page I call $myClass->destroy() to close the $link in the parent class. This works OK.

The problem is that when I instantiate AnotherClass.class.php which also extends Base, and is also used in the same pages, that when I call $anotherClass->destroy() before I call $myClass->destroy() it closes the $link in *both* $myClass *and* $anotherClass. This causes an error because $myClass should still be open for use.

What is $link in each Base class? Is it a reused connection? Is it an existing open connection? Is it a page scope connection? How should I get around this? Using true on the mysql open connection? Or never using destroy()?

I have a very simple HTML file containing PHP scripts. Even though
I enabled PHP, PHP scripts doesn't seem executing when
embedded in HTML files with .htm or .html extensions.
It only displays 'Toto' and not 'Tada' with the .html file
shown below.

It worked fine when I renamed the file with .php extension.
All my menu's built using .html file extension as I'm using
Yahoo! Site Builder. Is there any way I can get PHP scripts
working embedded in .html file?

Toto

8.Two program A and B are running in a multiprogramming environment. Program A outputs much data to printer. Program B produces very little output. Describe a suitable scheduling policy in this case, explaining your reasons.

9.An airline booking system makes use of a real-time OS. Define real-time and explain why it is necessary in the airline booking system.
This is a mechanism that interrupts at fixed intervals of real time, and is needed for accounting and scheduling purposes. In some systems multiprogramming makes use of a real-time clock which initiates interrupts to the operating system allowing it to allocate timeslices to programs. This technique can also be used to share CPU time among a number of a multi-access environment.

I have to use a lookup function for the following and I can't for the life of me figure it out.
Data:
Freshman 0 to <32 credits
Sophmore 32 to <63 credits
Junior 63 to < 94
Senior 94 or more credits.

Basically, I was given a spreadsheet and have to fill in all the columns using formulas and this is the only one I cant get. Credits start in E5, for example E5 contains 57 E6 contains 94 and so forth... i need to come up with a formula that will allow in G5, Sophmore to come up without typing it in, so if the credit count changes everything else will also automatically. I hope some kind soul can help me. This is proberly so easy, I am just so tired , been at it for 4 hours doing the whole spreadsheet. thanks in advance
