So that put it as a global function.
But I can again consider on that after completing the implement class
behavior of common.lib.php file
For just now I move PMA_mimeDefaultFunction() function to core.lib.php
file.

Hi Michal,
There are many places which are using functions in common.lib.php file.
After implement the class behavior for this file, all the other places
need
to call those functions using an object of
PMA_CommonFunctions class.
Even in the same file I may need to create several objects of the
PMA_CommonFunctions class. (files with global functions)
So I' thinking of using global variable (in $GLOBALS super global array)
to
store an object of PMA_CommonFunctions class and
introduce a global
function (may be under core.lib.php) to get that object by checking
whether
the global variable is set or not.
So that even inside the procedural code segments, that function can be
used.
Its highly appreciated if you can give me your
feedback on this approach.
Regards !
What you seem to want is a singleton [0]. In a few words: the
constructor is private, the instance is in a static variable and a
public getInstance method allows access to the instance. You can also
have a look at the PMA_Response class for a concrete example.
Bye,
Rouslan

Hi Rouslan,
Thanks for your quick and valuable information.
Singleton pattern definitely use only one object and it save the memory.
I'll use that.
Regards !
