PHP requests do not work via webviewer

I have created a .php website with embedded html code. Every 10 seconds the page makes a php seed request but when I stream the page via webview it doesn't make any requests at all. Html code thinks and js code but no php requests are made. Why is that so? Everything works on the regular web browser, but not when I drag it into the app invetor. I don't want the source code directly in app inventor this as it should be easy to update the code directly, therefore I want to stream the website. Anyone know how to can solve it?

Addition: Noticed now that it makes a request when opening the app but no more after that

You need to show your html/php/js, without that we know as much as you do.

In addition to what Tim says, you cannot have PHP code in your phone app, as PHP is strictly a server side language.
