...this links to the current page, and it includes two "get" method variable names and values. So if the user clicks on this link, they'll go to the same page they are already on, but this time there will be two $_GET variables set and available for use in your script: $_GET['topicid'] set to the value of $topicid and $_GET['page'] set to the value of $pagenext.
$php_self
What does this do ?
<a href=’$PHP_SELF?topicid=$topicid&page=$pagenext’>
if I and running prog.php
1)
when i click on this link will it re-run it?
2)
the value seems to have two parts
is the & in it just part of the variable name
or is it an opperand ?
$topicid&page does it mean $topicid & page ?
I’d like to understand this bit of code !!
