Hi All,
I have already create a class for display_tbl.lib.php andPMA_getDataCellForBlobField() in master used the PMA_mimeDefaultFunction() function as a global function. EX : $str = 'PMA_mimeDefaultFunction'; $str($parameters);
I have moved the PMA_mimeDefaultFunction() from display_tbl.lib.php
(in
master) to common.lib.php file due to the way it has used inside display_tbl.lib.php.
Now I'm implementing class behavior in common.lib.php file. So can anyone tell me a file, which contain global function, to where
I
should again move this PMA_mimeDefaultFunction().
Regards !
Chanaka, I believe that this function should not be global, as it's only called from other functions in libraries/DisplayResults.class.php, right?

Hi Marc,
Sorry for little bit delay to respond. I first try to use this function while it is inside the
PMA_DisplayResults
class. But if there is any field with transformations, it does not work
properly.
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.
Regards !

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 !
