I have a idea
if I can temporary store the generated excel file in server.
So I can make program to separate a fews parts of data to run fews times php script to write all data to excel
EG I have 1000 rows of data need to write into excel.
I write a php script separate each 100 rows data run once time of script and generate a excel file temporary into server
Then the script run 10 times. All data can input into excel in server. After that user can download the excel files
Can phpexcel can store excel file in server?
