Here is a small tips for you which you can use to upload such a large file using file field of the form and move_uploaded_file() function in PHP.

1) Create a .htaccess file in the root folder of web server.
2) Put the following code in side the .htaccess file and save it.

php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 200
php_value max_input_time 200

Now you can upload the file-size up-to 20MB in a simple way using file field in your html form and move_uploaded_file() function available in PHP. In the above .htaccess file, uploading capability is increased by the four parameter first one is maximum file size for uploading, second one is maximum size of the post data , third one is maximum time in seconds a script is allowed to run before it is terminated by the parser and last one is maximum time in seconds a script is allowed to parse input data such as like file uploads, POST and GET data.

You can change the above parameter to upload the bigger file size than 20MB.
