How to use store and use session variables across pages

Question

When one page is accessed  I would like to start a session and store a session variable    lt  php   session start         SESSION  myvar    myvalue     gt    Then from another page  I would like to check if that session variable has been stored    lt  php     session start        echo  1        if isset   SESSION  myvar                   echo  2           if   SESSION  myvar       myvalue                       echo  3               exit                       gt    This code does not work for me

Reasoning from the comments to this question  it appears a lack of an adjusted session save path causes this misbehavior of PHP   s session handler  Just specify a directory  outside your document root directory  that exists and is both readable and writeable by PHP to fix this

Try this  First Page   lt  php    session start         SESSION  myvar    myvalue     gt    Second page    lt  php    session start       echo   SESSION  myvar       gt

In the possibility that the second page doesn t have shared access to the session cookie  you ll need to set the session cookie path using session set cookie params    lt  php session set cookie params   lifetime    shared path to files      session start      SESSION  myvar    myvalue     And   lt  php session set cookie params   lifetime    shared path to files      session start    echo  1    if isset   SESSION  myvar           echo  2       if   SESSION  myvar       myvalue               echo  3           exit

Every time you start a session  applies to PHP version 5 2 54   session start   creates a new session id   Here is the fix that worked for me   File1 php  session id  mySessionID      SET id first before calling  session start session start      name    Nitin Hurkadli     SESSION  username      name    File2 php  session id  mySessionID     session start      name     SESSION  username    echo  Hello       name

All you want to do is write --- session start    ----- on both pages     lt  -- first page -- gt   lt  php   session start         SESSION  myvar      hello     gt    lt  -- second page -- gt   lt  php     session start        echo   SESSION  myvar       it will print hello     gt

Sessions Step By Step   Defining session before everything  No output should be before that  NO OUTPUT   lt  php session start      gt   Set your session inside a page and then you have access in that page  For example this is page 1 php   lt  php      This is page 1 and then we will use session that defined from this page      session start          SESSION  email    email example com     gt   Using and Getting session in 2 php    lt  php    In this page I am going to use session     session start      if   SESSION  email       echo  Your Email Is Here                gt     NOTE  Comments don t have output
