callback URL and copy rename file

Bonjour, I am looking for a PHP coder. This is the job: I need a callback URL in PHP You must reply "OK" and then get the parameter "IMSI" I have a .PDF about the API if you have questions. By the way I am looking for: 1 .HTML page with 1 text box and 1 button 1 .PHP script On my server I have a file [login to view URL] When user type something in the text box and then click on the button it will copy [login to view URL] and rename the file from [login to view URL] to bonjour_#content_of_textbox#[login to view URL] Then redirect user to this new URL. Example: I type france in the textbox and then I click on the button the script in PHP will copy [login to view URL] as [login to view URL] and your script will redirect the user to [login to view URL] Thank you in advance!
