Cannot get a session counter to work

[tedpottel]

Hi
I cannot get sessions to work.
I have the following code
</body>

<?
session_start() ;
$counter++;
print "You have visited this page $counter times during this session";
session_registe r("counter");
?>
</html>

And get the following output
Warning: session_start() [function.sessio n-start]: Cannot send session
cookie - headers already sent by (output started at /home/ted/
public_html/store/test/testsession.php :15) in /home/ted/public_html/
store/test/testsession.php on line 16

Warning: session_start() [function.sessio n-start]: Cannot send session
cache limiter - headers already sent (output started at /home/ted/
public_html/store/test/testsession.php :15) in /home/ted/public_html/
store/test/testsession.php on line 16
You have visited this page 1 times during this session

What is going wrong????

A lot:

* You can't have any output before the session_start() call. Move it to
the top of the page _before_ any HTML. This should fix the "headers
already sent" issue.

* Use <?php instead of <?. Short open tags are unreliable.

* Check your php.ini and make sure that error_reporting is set to E_ALL
and display_errors are on. Your code above should throw an E_NOTICE
error.

* You don't need session_registe r() anymore. Use something like this to
properly initialize and increase the counter:

session_start() ;
if (!isset($_SESSI ON['counter'])) {
$_SESSION['counter'] = 1;
} else {
$_SESSION['counter']++;
}

Later simply use

print $_SESSION['counter'];

to output it.
