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";

if(!isset(
$_SESSION['count'])){
   
$_SESSION['count'] = 1;
}else{
   
$_SESSION['count']++;
}

$_SESSION['count'];
//above, $_SESSION['count'] will keep increase;
?>

demo2
<?php
session_start
();
if(!isset(
$_SESSION['count'])){
   
$_SESSION['count'] = 1;
}else{
   
$_SESSION['count']++;
}
session_abort();
echo
$_SESSION['count'];
//$_SESSION['count'] will always be 1;
?>
