Search and replace php script

I need a simple Search field and submit button

When you enter a search term and you click submit it should replace “keyword phrase” in a text file (see below )and display it on the next page as a .php file (result page).

Should be easy to make for someone with general PHP knowledge.

Source code is here below where the “”keyword phrase should be replaced.
