[Resolved] sessions--- whats the deal with php5?

[beedge_returns]

Hi all

I have just completed a php/MySQL website:

http://www.limerickrocks.ie

As a finishing touch I wanted to ad in a counter that I had coded in an older website (pre PHP 5).

The code was as follows:

session_start();
if(!session_is_registered('click')){
	$serverdate = date("l, d m h:i a");
	$output= $_SERVER['HTTP_REFERER']; 
	$agent= $_SERVER['HTTP_USER_AGENT'];
	include "connections.php";
	mysql_connect($DBhost,$DBuser,$DBpass);
	mysql_select_db("$DBName");
	$result = mysql_query("SELECT * FROM `count` WHERE id_count = 1");
	$click = mysql_result($result,0,"click");
	$click+=1;
	mysql_query("UPDATE `count` SET click=$click WHERE id_count=1");
	mysql_query("INSERT INTO `count` (click, id_count, camefrom, agent, time) VALUES ('$click', '$id_count', '$output', '$agent','$serverdate')");
	session_register('click');
}

The problem is that the server uses php5 and it gives me the following message when I go to the page:

Warning: Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

The Thing is that the counter works fine so I would kinda like to leave the code as is.

I dont have access to change the configuration of php on the server so I cant just turn the compatability warning off.

Whats the best way for me to get around this problem??

Any help greatly appreciated,

maybe this is the problem try in place of
if(!session_is_registered('click')){
try
if(!isset($_SESSION['click'])){

Hi

Also make sure if register_globals is on or off in the php.ini file. If it’s off you can't use session_register().
Peppeto's why should work then.

As I said I havnt got access to the php configuration.

Ive replaced the first line of code with peppetos suggestion, but I am getting the same message at the bottom of the screen...
If session_register() wont work, what can I do instead?

You use the $SESSION super global. It's a very special array which (if you've done a session start) will write to session when you write to it. So,

<?php
session_start();
$_SESSION['variable']='value';
//you now have the session variable|s:5:"value"
?>
//next file
<?php
session_start();
echo($_SESSION['variable']);
//prints "value"

Thanks all,

The problem is resolved as follows:

session_start();
if(!isset($_SESSION['click'])){

$serverdate = date("l, d m h:i a");
$output= $_SERVER['HTTP_REFERER']; 
$agent= $_SERVER['HTTP_USER_AGENT'];
include "connections.php";
mysql_connect($DBhost,$DBuser,$DBpass);
mysql_select_db("$DBName");
$result = mysql_query("SELECT * FROM `count` WHERE id_count = 1");
$click = mysql_result($result,0,"click");
$click+=1;
mysql_query("UPDATE `count` SET click=$click WHERE id_count=1");
mysql_query("INSERT INTO `count` (click, id_count, camefrom, agent, time) VALUES ('$click', '$id_count', '$output', '$agent','$serverdate')");
$_SESSION['click']=$click;

}
