Hello friends,

  file1.php
session_register("var1");
echo "session created";
$HTTP_SESSION_VARS["var1"]=0;


file2.php
echo $HTTP_SESSION_VARS["var1"];
$HTTP_SESSION_VARS["var1"]=$HTTP_SESSION_VARS["var1"]+1;

whats wrong with these two files. First file didnt produce any error. The second file didnt display any value.

I used $_session["var1"] instead of $HTTP_SESSION_VARS["var1"]

but no display.

pls, clearify my problem. how to manage sessions?

thanx in advance

Don't forget that variable names are case sensitive. $_session is not the same as $_SESSION. The latter is the correct way to reference the session superglobal. Don't use the long names... $HTTP_*_VARS... these aren't going to exist in PHP 5. If you are using PHP prior to version 4.2.0.. write a script that transfers the old long variable names to the short ones. If you need us to elaborate more on that just ask.

<?php

// file1.php

session_start();

$_SESSION["var1"] = (int) 0;

echo "session created";


?>
You need to make a call to session_start() at the beginning of every page which requires the use of sessions. This function will create a cookie and alter the outgoing HTTP response headers and as such should be called before any output is sent from the page. And the opening <?php delimiter should have no white space before it. Session register should not be used... (PHP 4.2.0 and greater) here is a page that discusses why.

<?php

//file2.php

session_start();

echo $_SESSION["var1"];

// Two plus signs will post-increment and assign that value to the variable
$_SESSION["var1"]++;

?>

This method also requires that you have cookies enabled in your browser. Otherwise you will need to pass the session id to each page that requires use of sessions via a url embedded argument.

echo "<a href='file2.php?".SID."'>file 2</a>";

or

echo "<a href='file2.php?sid=".session_id()."'>file2</a>";

And finally the PHP manual page on sessions
