To better understand this function you should execute this code first :

<?php
    // First of all choose your path , For e.g. C:/session
    session_save_path('Your Path here !');
   
    session_start();
   
    // Define a Session Variable
    $_SESSION['Key'] = 'value' ;
   
    Var_dump(session_status() == PHP_SESSION_ACTIVE);
   
    // Output : bool(True) , it means you have an open session !
?>

Then you should execute this code :

<?php
    // Choose the path that you used it in first part 
    session_save_path('Your path here');
   
    session_start();
   
    // If you want to close session and keep your original data in your path , you should use session_abort()
    session_abort();
   
    var_dump(session_status()== PHP_SESSION_ACTIVE);
   
    // Output : bool(False) , it means your session closed .
?>

So if you have an open session , session_abort() will simply close it without effecting the external session data , so you can reload your data again from your path that you chose .
