save the display shown in browser as html-file using php ?

Say we display (echo..) the output of a php-script in the browser. We can save what we see in the browser using the browser-menu (file -->save as--> anyname.htm) and we have a html-file. Now say we have a script allowing to add and edit records to a database, with the record-data shown in a form (html-page). And ´say that after adding a new or editing a record our script shows the newly added or edited record. Is there a php-funktion we could add to this recall-script that also saves the output as html (without any user-interaction). Thanks to everybody who can contribute a thought on that. Kind regards Helmut
