Fetching more than 10000 rows in PHP Custom Script

Content

I am fetching a report in php which has more than 10000 rows.

While i can create a loop and get the data more the rows more than 10000 also, but I am not able to merge the all the rows.

Is there a way in PHP where we can merge the report result?

Code snippet given below.
