php session array : What's wrong in this code


Dear ALL

PLEASE HELP


I am trying to accumulate values in an array.

I am happy with the value stored in variable page_views

However the array defines is initialised...

May be I had not defined properly

Can any one help me to store valued in session array....

May be (rather certainly) there is an error..

Thanks in advance
Vikas Athavale

<?php
session_start();
session_register("page_views");
session_register("arv");

$arv=array();

$k=count($_session["arv"]);
$k++;
echo "<br> count= ".$k."<br>";
$_session["arv"] [$k]= $page_views;

echo "<br>value stored in session var arrayvariable = ".$_session["arv"] [$k] ."<br>";
$page_views++;

echo "<br> _session count= ".count($avar)."<br>";

echo "You have viewed this page ";
echo $page_views;
echo " times(s).";

?>

If im understanding it, looks to me that everytime you declare $arv=array(); you are essentially wiping out the old data with an empty array.

Try testing for it being equal to null before declaring it as an empty array... no need to declare it if its already stored in a session.

The biggest mistake in your code is that you are tring to access global variables the wrong way.. all the global variables are with capitalized letters, like: $_GET, $_POST, $_SESSION, $_COOKIES, $_SERVER, etc..

Note: $arv isn't the same as $_SESSION['arv']

And at:
PHP Code:
$_SESSION["arv"][$k]= $page_views
You haven't set the $page_views so you assign empty value for $_SESSION["arv"][$k]

Hopefully you understand me
