  • return bool true if the list contains the given token, otherwise false
public abstract entries () : ArrayIterator
 

Returns an iterator allowing you to go through all tokens contained in the list.

  • return ArrayIterator
public abstract item ( int $index )
 

Returns an item in the list by its index (returns null if the number is greater than or equal to the length of
the list).

  • param int $index the zero-based index of the item you want to return

public abstract toggle ( string $token , ? bool $force = NULL ) : bool
 

Removes a given token from the list and returns false. If token doesn't exist it's added and the function
returns true.
