How to fire a PHP function on button click?

[BaseballGraphs]

Hello,

I have a PHP function that currently triggers when the page loads.

I would prefer that this function is only triggered when someone clicks a button.

How can I accomplish this?

Thanks for any of your help!

you cannot directly trigger a PHP function by a user interaction (PHP - server, User - client). what you can do is call a PHP script via AJAX (which itself is triggered by the user interaction) and insert the returning code this way.
