By far I am not an expert but that's pretty easy!
<form action="path/to/filename.php" method="post">
<input type="text" name="nameyourposteddata" />
(and/or other form inputs/tag names incl types & names)
(do the same for each additional tag, with proper post variables, and for strings of proper formatting characters--newlines, etc.)
then close your php with the tag and follow it with the html you want to put to the browser.
If you need more thorough help: www.w3schools.com/php/php_forms.asp
Hope this helps.
