I am getting an empty array .Here ajax post is coming fine. I am not getting what is the error , For small size image For large size image Any suggestion ? Thank you

Have you check to see what the max upload size is in the server config files? — Blinkydamo, Nov 02 '16 at 11:23
Sounds like you may need to increase the upload limit on the server — Rory McCrossan, Nov 02 '16 at 11:23
yes i have checked ,it is 128M and my post_max_size = 8M @Blinkydamo — sradha, Nov 02 '16 at 11:24
Have you changed both of these to what you need? `; Maximum allowed size for uploaded files. upload_max_filesize = 40M ; Must be greater than or equal to upload_max_filesize post_max_size = 40M` — Blinkydamo, Nov 02 '16 at 11:26
That might be your issue then, change the post_max_size to 128M and reload the server. — Blinkydamo, Nov 02 '16 at 11:29

By configuration, PHP only allows to upload files up to a certain size.

You can edit your php.ini file and set

memory_limit = 32M
upload_max_filesize = 24M
post_max_size = 32M

then restart your server

If you are trying to upload file greater than 2 GB. Then you should consider the memory usage of such a script.

Then you have to user chunked upload.More details : Handling plupload's chunked uploads on the server-side and here : File uploads; How to utilize "chunking"?
