when i put this code in my computer:

<?php
session_register("view1count");
session_register("view2count");
session_register("view3count");
session_register("view4count");
?>
<?php
//page_count.php
if (!$view1count) $view1count = 0;
if (!$view2count) $view2count = 0;
if (!$view3count) $view3count = 0;
if (!$view4count) $view4count = 0;
echo "<HTML><HEAD><TITLE>Web Page Hit Counter</TITLE></HEAD><BODY>";
if ($whichpage) {
echo "You are currently on page $whichpage. \n";
$GLOBALS["view${whichpage}count"]++;
}
for ($i = 1; $i <= 4; $i++) {
if ($whichpage == $i) {
echo "<A HREF=\"$PHP_SELF?".SID."&whichpage=$i\">Page $i</A>";
} else {
echo "<A HREF=%22$PHP_SELF?".SID."&whichpage=$i/">Page $i</A>";
}
echo ", which you have chosen ".$GLOBALS["view${i}count"]." times. \n";
}
echo "\n\n \n\n";
echo "</BODY></HTML>";
?>

warning message appeared to me, but when i uploaded it (http://members.lycos.co.uk/aymenplusplus/page_count.php) every think is ok but when i press the first link for example i don't know what happened... why?

Firstly, I dont know if it matters, but put { and } in your if statements.

Secondly, and I dont know If this is right, you should change

${i} to {$i} and similar instances.

If this doesn't work, please post the error so that I know what is going wrong.

echo "<A HREF=%22$PHP_SELF?".SID."&whichpage=$i/">Page $i</A>"

should be

echo "<A HREF=\"".$PHP_SELF."?".SID."&whichpage=".$i."\">Page ".$i."</A>";

Also, don't forget the session_start();

The code is kinda messy though

Right, that means you have no /tmp folder to store your session data. I am having the same problem, but I am using phpdev.

I just remembered, you can change the name of the dir in php.ini

by the way, what is meaning of "stateless", i searched it in the dictionary and i didn't find it?

stateless and state normally refer to an object and its state...look it up in an OO based language, I can't think of a way to describe it.
