Ka¿da tablica ma wewnêtrzny wska¼nik bo swojego "bie¿±cego" elementu,
|
|
który jest inicjalizowany do pierwszego elementu wstawionego do
|
|
tablicy.

</para>
|

<para>
|
|
Funkcja <function>current</function> po prostu zwraca warto¶æ elementu
|
|
tablicy, na który aktualnie wskazuje wewnêtrzny wska¼nik. Nie przesuwa
|
|
ona wska¼nika. Je¶li wewnêtrzny wska¼nik jest poza koñcem listy
|
|
elementów,
|
|
<function>current</function> zwraca &false;.

Nie bêdziesz móg³ odrózniæ koñca tablicy od elementu &false; typu
|

<type>bool'owskiego</type>. Aby poprawnie przej¶æ przez tablicê,
|
|
która mo¿e zawieraæ elementy &false;, zobacz funkcjê <function>each</function>.
