Question

How is it possible to allow a user to create a webpage containing some html, based on their entries in a form? ie. I would want them to be able to input a name and when the button is clicked, a webpage called that name would be created. I imagine that this must be possible in php, but what functions/code would I be using?

Thank you!

This can pose big security risks in the first place, anyways, suppose form is submitted with html text, you can go about something like this:

$handle = fopen('file_name.html', 'r+');
// write to file
fwrite($handle, $_POST['fieldname']);
close($handle);

Note: You got to consider XSS and other security issues because you are allowing users to create pages. Bad guys can exploit it easily.

Resoures:

PHP File Handling Functions

XSS

Finally, a must read PHP security guide:

Idea:
Just allow them minimal of customization and use a pre-made page where you could insert this user data. Ofcourse as said, you need to sanitize the user-submitted data and consider security issues.
