I currently have a php application in development on an AWS EC2 instance but I\'ve decided to move it to Elastic Beanstalk to take advantage of the autoscaling functionality
You can also add this to your elastic beanstalk project.config file:
"/etc/httpd/conf.d/php.conf" : content: | php_value session.save_path "/tmp"
that will just set the session save path for you
