Okay, I really don't have any idea on how to explain this.
I have a session array:
$_SESSION['users']['currentuser']['username'] = 'stijn';
this array is build dynamically. So, i need to remove some values of this array also dynamically.
for this, I have a function:
function removeSessionValue($keys) {
$keys = explode(':', $keys);
var_dump(array_keys($_SESSION));
$tempArray = array();
$reference = &$tempArray;
foreach ($keys as $key) {
$reference[$key] = array();
$reference = &$reference[$key];
}
$multiArray = $tempArray;
}
function call= removeSessionValues('users:currentuser:username');
So now I have the originarray (session) and the array to check if the session exists (built by the function).
Is there any way, on how I can unset the $_SESSION['user']['currentuser']['username'] ?
Important note, we don't know what values will be passed in the function, as also we don't know what sessions exists, as everything is ultradynamic ...
A simple way is use eval():
function deepUnset(&$array, $keys)
{
$cmd = 'unset($array["'.implode($keys, '"]["').'"]);';
eval($cmd);
}
// Example:
$_session = array(
'users' => array(
'currentUser' => array(
'username' => 'stijn',
),
'otherUser' => array(
'username' => 'james',
),
)
);
echo '<pre>';
print_r($_session);
deepUnset($_session, array('users', 'currentUser', 'username'));
print_r($_session);
echo '</pre>';
