EDIT  After your comments  I understand that you want to pass variable through your form   You can do this using hidden field    lt input type  hidden  name  var  value   lt  php echo   var    gt    gt     In PHP action File    lt  php     if isset   POST  var      var   POST  var      gt    Or using sessions  In your first page      SESSION  var    var    start session    should be placed at the beginning of your php page   In PHP action File   if isset   SESSION  var      var   SESSION  var      First Answer   You can also use  GLOBALS    if  isset   POST  save exit           echo  GLOBALS  var          Check this documentation for more informations

Try that  First place  global  var   var    value     Second place  global  var  if  isset   POST  save exit           echo  var       Or if you want to be more explicit you can use the globals array    GLOBALS  var      test       after that echo  GLOBALS  var      And here is third options which has nothing to do with PHP global that is due to the lack of clarity and information in the question  So if you have form in HTML and you want to pass  variable  value to another PHP script you have to do the following   HTML form   lt form action  script php  method  post  gt       lt input type  text  value   lt  php echo  var  gt   name  var    gt       lt input type  submit  value  Send    gt   lt  form gt    PHP script   script php     lt  php   var     POST  var    echo  var     gt
