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";
