wordpress cookies wild card

2 Views

wordpress names cookies like

the part after _in is different for every user. Is there a way I can use it with wild card in 

$_COOKIE["wordpress_logged_in_bbfa5b726c6b7a9cf3cda9370be3ee91"]

so something like 

$_COOKIE["wordpress_logged_in_%"]

  1. You will have to loop through the entire $_COOKIE array to see if it matches the pattern:

    $matches = array();
foreach($_COOKIE as $key => $value) {
  if(substr($key, 0, 20) == 'wordpress_logged_in_') {
    $matches[] = $key;
  }
}
//$matches now contains the key of all matching cookies
