PHP Automatic Self Trigger
<p>Not sure if I understood the use/purpose of PHP entirely, but what seems to me that a .php file only executes when it is being called/executed by something before it, could be a html or a php file.</p>

<p>A thought, is it possible that a php file written, and it would just be activated by its own, example over a duration span of time, every week or so it would do something?</p>

<p>Thanks for looking...</p>
