Hi,

If u running ur own local pc then just download and install WAMP or XAMPP.

It has no need to make changes in php.ini and some other files.

If u r on ur remote server then verify either the host has gave u the permission to edit or not.

If no then ask ur host to do for u.

Thats all.

Hope this will help u.

OK,

 

I uninstalled php,mySql, turned off iis,

then installed wamps.

 

I put this before html Page 1

 

<?php

session_start();

$_SESSION['views']=0;

?>

 

I put this in the middle of <?PHP bla bla bla  ?> Page 1

 

$_SESSION['views']=10;

header("location: Page2.php");

 

I put this before html Page 2

 

<?php

session_start();

?>

 

I put this in the middle of <?PHP bla bla bla  ?> Page 2

 

echo "Pageviews=". $_SESSION['views'];

 

response on the screen is

 

Pageviews=

 

But no error message.

(i) Error I see when (page 1) loads:

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\wamp\www\MyPHP\Member\0301SignUp.php:2) in C:\wamp\www\MyPHP\Member\0301SignUp.php on line 3

 

(ii) Error I see when I Input values into the feild:

 

Warning: Cannot modify header information - headers already sent by (output started at C:\wamp\www\MyPHP\Member\0301SignUp.php:2) in C:\wamp\www\MyPHP\Member\0301SignUp.php on line 60

 

Error (ii) did not appear when I used IIS, may be I twitched something in my code lately, thus this error, but the code seems ok.

 

Thanks for your offer to help.

Try this:

<?php
ob_start();
session_start();
$_SESSION['email']=0;
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>
<body>
The rest of code

 

Also do it for 2nd page, and then let me know what happened.

U r welcome.

 

Actualley in php u have to put the sessions before the html is parsed.

So it means that at the top of the page before html or other php code.

Other if u put ob_start();

Then u can use session_start(); in every page.

Now i will recomend u to make a separate php page as(session.php) and

put all ur session variable there and include it on every page u want to put the

session.

But remember u have to include that file at very top of the page like:

<?php
require_once('session.php');
?>

 

Glad to solved out ur problem.
