; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes

Answer 1

In PHP, check if folder is writable, if not,

if ( ! is_writable($currentPath.'/'.$fileName)){

    echo 'Not writable!!!';
}

Then, go to ec2 via terminal, you need access, and use command

sudo chown -R www-data:www-data /var/www/html/YOUR-PROJECT-FOLDER
