Unset all session variables with similar name

Question

I\'m using some $_SESSION variables for filtering many query records that have a similar name (ex. $_SESSION[\'nameFilter\'] or $_SESSION[\'cityF

Answer 1

You need to check for every exist session and check it name. Please check below example code.

 $sessValue){
    //Check for session name exist with 'filter' text...
    if (strpos($sessKey, 'filter') !== false) {
        unset($_SESSION[$sessKey]);//Unset session
    }
}

echo '
' . print_r($_SESSION, TRUE) . '
';
/*Output...

Array
(
    [fourtilter] => four
)
*/
?>

May this help you well.
