HTML form action
—Action is used to give reference/link of another page.
—If we want to separate the business logic (PHP script)
from Presentation layer (HTML script) then we use Action attribute of Form .
—It reduce the complexity of bulk of codes. Because All
scripts are separately define on their own page.
—In the previous Form Post method PHP script
and HTML script were define on the same page ,so it show the design part with
the output of program.
But using Action property HTML script define on a separate page and Business logic(PHP script) on another separate page.
