I run a php script from xampp portable on windows. The script takes over a minute. Recently, the script is having flush() problem, as echo statements are not immediately displayed. The script used to work fine earlier with no buffering problem.
Interestingly, I ran the same script copying the xampp portable to another system and the flush statements were working without any problem. Same code, Same xampp portable.
What could be the reason?
I figured out that the problem is with antivirus. I recently switched to Bitdefender from Avast. When I switched back to Avast, the problem disappeared miraculously. So, i guess antivirus is also a factor here.
