Php edit form input without connecting to database
===

I have a input form like this:
<`input type="text" name="etest" value="<? echo $test1;?>"/>` and `$test1 = "something";`

How can i edit the input value on submit, without connecting to database.

If i change the word (with: "summer"), and i click submit, to refresh the page and the input value to have now "summer".

I know is a newbie question but i hope someone can tell me.
Thx in advance
