    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 .

    session_abort()  closes the current session and discards the changes applied to Session array in the current page  , it doesn't delete the session file 
    let me explain with one example.
    page 1.php :
    <?php
    session_start    ();
    $_SESSION['city']="Sydney";
    echo     "<a href=\"2.php\"> page2</a>";
    ?>
    when you open this page , a session file is created on the server (to find out where session files are saved run "echo session_save_path()" )  with the name of session_id  and the content of  the variable :

      sess_o22iabs75j93uhc7i4jf1lecjk  (file name)
    city|s:6:"Sydney";               (content)

    if we go to 2.php containing this code :

    <?php
    session_start    ();
    $_SESSION['country']="Australia";
    echo     session_encode();
    session_abort();
    session_start();
    echo     "<br>".session_encode();
    ?>

    when session_abort is executed , the session is closed and the change which here is the 'country' element of Session array is discarded . 

    Output : 
    city|s:6:"Sydney";country|s:9:"Australia";
    city|s:6:"Sydney";
