How can I call student/index.php from teacher/index.php?
in your teacher/index.php write
header("Location: ../student/index.php"); // this is incase you want to go to that page
require_once('../student/index.php'); // incase you want to include that file
require '../student/index.php';
This will 'call' the script. If the script has a return value, then simply make an assignment statement on the left side of the require statement.
$ret = require '../student/index.php';
In your teacher/index.php use this code at top
header("Location: ../student/index.php");
You can also use pecl_http (if available) and the function http_redirect.
