First of all you should execute this code :
<?php
    session_start
();
   
$_SESSION["A"] = "Some Value";
?>

then you should execute this one :

<?php
    start_session
();
   
$_SESSION["A"] = "Some New Value"// set new value

   
session_reset();  // old session value restored
   
echo $_SESSION["A"];

   
//Output: Some Value
?>

That is because session_reset() is rolling back changes to the last saved session data, which is their values right after the session_start().

first create a session variable

<?php
    session_start
();
   
$_SESSION["A"] = "Some Value";
    echo
$_SESSION["A"];

   
//Output: Some Value

    //if you need to rollback the session values after seting new value to session variables use session_reset()

   
$_SESSION["A"] = "Some New Value"// set new value
   
   
session_reset();  // old session value restored
   
echo $_SESSION["A"];

   
//Output: Some Value
?>
