How do I delete an item in an array that is in a session? php

I have a session that contains an array. The array contains the following data:

Array ( 
    [0] => /assets/img/user_photos/thumbs/9c2310c2def9981221ec37cbbafe0370.jpg 
    [1] => /assets/img/user_photos/thumbs/286b59eb3dafe2e0cf0df50e45f10250.jpg 
    [2] => /assets/img/user_photos/thumbs/4e6012cc396252594d2a05850b0a35ae.jpg 
    [3] => /assets/img/user_photos/thumbs/49ce9031319203c1911c0b9789a83ffc.jpg 
    [4] => /assets/img/user_photos/thumbs/da21379f3dc80541a087e1c4db5f929a.jpg 
    [5] => /assets/img/user_photos/thumbs/1f46378fdd7dcf7fda580e50ca92a2d0.jpg 
)

I would like to delete an item from this array. How is this possible when the array is stored in a session?

You can use 

unset($_SESSION['Array_name']['index_tobe_delete']);

OR 

$_SESSION['Array_name']['index_tobe_delete'] = "" ;

in a non-hacked Environment the superglobal-Array $_SESSION references all data in the session. So you could delete an entry by this:

unset($_SESSION['indexToYourArray'][0]);

(you didn't mention in which session variable your index is stored). If the array is the session content the code should read:

unset($_SESSION[0]);

You can use unset()

Eg:

$_SESSION['abc'] =  Array ('foo','bar');

to delete bar:

unset($_SESSION['abc'][1]);
