+1? How!?!

hi how do i plus 1 to a var eg

<?php
$curpg = $_GET['curpage'];
$nxtpg = ''; // here is where i am stuck i want to do curpage +1 but i don't know how

I have searched this in Google and it comes up with things like ' Adding PHP To A Webpage! '

Please Help!

$curpg = $_GET['curpage'];
$nxtpg = "$curpg++";
this work?

that just adds ++ to the end of my URL parameter
Look:
index.php?curpage=1++

Is this question some kind of joke?

$curpg = $_GET['curpage'];
$nxtpg = "$curpg++";
this work?


There's no need for those double quotes.

This works:

$curpg = intval( $_GET['curpage'] );
$nxtpg = $curpg + 1;

cheers

To increment a number variable rafiki was correct you just need to use the ++ operator. Just lose the quotes around it otherwise it will treated as a string which is why you got the characters ++ at the end.

$curpg = curpg + 1 is the same as $curpg++.

ok sos!
