Configuring php for handling large file upload

Cut it short, what I need is to configure my nginx-php to be able to handle around 200M file upload.
So here are the configuration changes I need to make:
1. nginx.conf
    usually the file is placed in /etc/nginx/nginx.conf.
    The parameters to add inside http are:
    - client_max_body_size: specifies the maximum accepted body size of a client request
    - client_body_timeout: sets the read timeout for the request body from client
    http {

        ##
        # Basic Settings
        ##

        client_max_body_size 200m;
        client_body_timeout 600s;
       
        ....
   }

2. php.ini
    Since I use php5-fpm, this file is placed in /etc/php5/fpm/php.ini
    The parameters to change is:
    - post_max_size: Sets max size of post data allowed
    - upload_max_filesize: The maximum size of an uploaded file
    - max_execution_time:This sets the maximum time in seconds a script is allowed to run before it is terminated by the parser.
    - max_input_time:  This sets the maximum time in seconds a script is allowed to parse input data, like POST and GET.


After changing those variables, restart both nginx and php5-fpm and you're done!
