How to write a string to execute PHP code on click?

Here is more specific:
there is php-code:

<?php echo do_shortcode( '[browser-shot url="http://mail.ru/" width="700"]Add Caption[/browser-shot]' ); ?>

--- A screenshot is taken here.
You need to make this process run when the button is pressed.

Answer 1

Make an empty form, the button will be Submit, and the action is this code of yours.

Answer 2

make a button and put a request on it, so the php script will run without reloading the page (maybe this is important)
