But in this case we will have to create seperate php file for each function.
Is there any way to write few php functions in one file and call one of them as required?

Yeah for this purpose you have to use the isset function i am giving you the syntax for that........
<?php

if(isset($_POST["submit']))
{

#Put Your code Here

}

?>
Put this at the top of the page. And all the code written in the if block will be work when the submit button is clicked.
