PHP fetching same records again and again
NOTE: Please don't mark my question duplicate.
I am trying to fetch new records while "Load More" button is pressed.
The problem I am facing here is that I am unable to change the values of $Limit
and $offset
variables and as a result, the same records are being fetched again and again.

Sorry, but i didnt saw the line in your code, where you are trying to rewrite your variable $offset.
If you are sendeing ajax request for geting new rows, you sholud to send in post variables for checking offset.
e.x your request may containg GET &page=2
'PAGE' - number of loaded pages, which you are saving in JS on user side.
On the user side in JS u must have the variable 'var page = 1' and When user pressed button 'MORE' you have to send AJAX request with GET parameter 'page' and increasing by 1 your variable 'var page';
In you server side by php you geting url param 'page' and multiply it on your limit, so you u will get your offset.
I didn't wrote all points, but i hope it will help u.
Is it possible using POST

'PAGE' - number of loaded pages, which you are saving in JS on user side.
On the user side in JS u must have the variable 'var page = 1' and When user pressed button 'MORE' you have to send AJAX request with GET parameter 'page' and increasing by 1 your variable 'var page';
In you server side by php you geting url param 'page' and multiply it on your limit, so you u will get your offset.
I didn't wrote all points, but i hope it will help u.
Is it possible using POST

Sorry, but i didnt saw the line in your code, where you are trying to rewrite your variable $offset.
If you are sendeing ajax request for geting new rows, you sholud to send in post variables for checking offset.
e.x your request may containg GET &page=2

You seem to use
global
quite a bit, generally I would discourage this unless you really need to. Passing parameters to a function makes it more flexible and testable.– Nigel Ren

@PrashantDeshmukh..... this is fetching a row from the database, so assignment is correct.
