You can either store it in the $_SESSION array or include the script in which you want to use the variable.
When you want to use variable $var in script newscript.php, you can include it:[php]]<?php
... some coding ....
$var = 'value';
include('newscr ipt.php');
... some more coding ....[/php]
See the following threads
about passing variables between scripts using the $_SESSION array.

it is not working. can u tell me where i m going wrong?Comment

Please specify what is not working? I see scripts login.php and fetch.php. Who is calling who? And where is script validate1.php? Because that is the script the login,php submit s to and the script that received the userid from the form in its POST array.
Code in login.phpwill not work because you have not assigned the username to the $_SESSION array as far as I can see from any script.Code:session_start(); $username1=$_session['username'];
So the question is: what script submits to what script? And where is validate1.php?

this is my validate.phpOriginally posted by ronverdonk
[PHP]<?php
$passwords = array("ajohari" =>"anurag",
"knaveen" =>"naveen",
"anu" =>"anu");
if ($password == $passwords[$username]){
//setcookie("user name", $username, time()+1200);
header("locatio n:/myphp/profile.php");
exit();
}else{
//setcookie("user name", "", time()-3600);
echo "<H2>Invali d user name or password: access denied.</H2>";
}
?>[/PHP]
how can I store the value of username in a session array?
login script is calling validate.php and after that fetch.php is called.Comment

It is exactly as I told you:
[php]<?php
session_start() ;
$passwords = array("ajohari" =>"anurag",
"knaveen" =>"naveen",
"anu" =>"anu");
if ($password == $passwords[$username]){
$_SESSION['username'] = $username;
//setcookie("user name", $username, time()+1200);
header("locatio n:/myphp/profile.php");
exit();
}else{
//setcookie("user name", "", time()-3600);
echo "<H2>Invali d user name or password: access denied.</H2>";
}
?>[/php]
