The code for both rnheader.php and rnmembers.php use cod <a href='rnmessages.php?view=$view'>.

I've looked elsewhere on the internet and it appears that view/$view is a parameter/value pair, but I can't find anywhere in the book where this technique is used or explained.

Also, rnmembers.php uses "if (isset($_GET['view']))", yet nowhere in the code is the get method used in a form. How is a _GET array called if the get method hasn't been used in a form?

Thanks.

Here i try explain this code : <a href='rnmessages.php?view=$view'>.
?view is the id of variable for the nnessages.php page and $view means this variable can get value of that page
"if (isset($_GET['view'])
this meaning is set the code for action on view button
