PHP is added into existing HTML pages and does not change anything except that which is inside the <?php ?> blocks. In other words, this is not a problem with PHP. In fact, your PHP looks like it should, probably, work.

<insert> is not an html element. You want <input>.

Also, that code is very messy and invalid. For example, you never close your <center> tag, and that element is not the modern way to center elements on the page anyway. And overusing <br> is not the best way to space things.

I don't mean for all of this to sound too harsh, but start with the basics and build on a strong foundation or you will have a lot more problems trying to do more complex things.
