what are the methods??? (the classical methods will not work and sql injection does not work)
but I tried to edit them ; I deleted them , but I went nowhere with it
any suggestion? any advice? any hint? any special technique
php scripts are held completely server side. What the browser sees is the result of the php script. You cannot "get" a php page (through normal means anyways).
SQL injection only works on a page where SQL queries are made to a database. Manipulating how input is filtered, you can make a SQL request to grab data you weren't supposed to. Various things can actually prevent this such as database user permissions and cleansing the input. I see no such query being made or any input taken.
Also, unless the example.com page has changed since this topic started, the path of the URL seems to be completely ignored. Am I missing something?
