U PHP-u postoji veci broj funkcija koje se koristi za kretanje kroz nizove. Ovo kretanje se vrsi pomocu pokazivaca niza, koji sadrzi tekucu lokaciju u nizu.
Primer:
<?php
$motori[0] = "suzuki";
$motori[1] = "ducati";
$motori[2] = "ktm";
print_r($motori);
/* ako zelite da odredite tekuci element niza
mozete koristiti funkciju current(). */
echo "Trenutni: ", current($motori), "<br />";
/* ako zelite da prebacite pokazivac na
sledeci element, koristite funkciju next() */
echo "Sledeci: ", next($motori), "<br />";
/* ako zelite da prebacite pokazivac na
prethodni element, koristite funkciju prev(). */
echo "Prethodni: ", prev($motori), "<br />";
/* ako zelite da prebacite pokazivac na
poslednji element, koristite funkciju end(). */
echo "Poslednji: ", end($motori), "<br />";
/* ako zelite da se vratite na pocetak niza,
koristite funkciju reset(), ili ... */
echo "Na pocetak: ", reset($motori), "<br />";
/* ... ili, ako zelite da se vratite na pocetak niza,
koristite funkciju reset(). */
echo "Resetovanje niza. <br />";
/* ako zelite da prikazete novi tekuci element,
koji je sada prvi element niza,
koristite funkciju current(). */
echo "Trenutni: ", current($motori), "<br />";
?>
Rezultat:
Array ( [0] => suzuki [1] => ducati [2] => ktm ) Trenutni: suzuki
Sledeci: ducati
Prethodni: suzuki
Poslednji: ktm
Na pocetak: suzuki
Resetovanje niza.
Trenutni: suzuki
In PHP there are a number of functions that are used to navigate through arrays. This navigating is done using the array pointer, which contains the current location in the array.
Example:
<?php
$motorcycles[0] = "suzuki";
$motorcycles[1] = "ducati";
$motorcycles[2] = "ktm";
print_r($motorcycles);
/* if you want to specify the current element of an array
you can use function current(). */
echo "Current: ", current($motorcycles), "<br />";
/* if you want to move a pointer to
the next element, you can use function next() */
echo "Next: ", next($motorcycles), "<br />";
/* if you want to move a pointer to
the previous element, you can use function prev(). */
echo "Previous: ", prev($motorcycles), "<br />";
/* if you want to move a pointer to
the end of element, you can use function end(). */
echo "End: ", end($motorcycles), "<br />";
/* if you want to return to the beginning,
of array, you can use function reset(), or ... */
echo "On the beginning: ", reset($motorcycles), "<br />";
/* ... or, if you want to return to the beginning,
of array, you can use function reset() */
echo "Resetting the array. <br />";
/* if you want to display new current element,
which is now the first element of array,
you can use function current(). */
echo "Current: ", current($motorcycles), "<br />";
?>
Result:
Array ( [0] => suzuki [1] => ducati [2] => ktm ) Current: suzuki
Next: ducati
Previous: suzuki
End: ktm
On the beginning: suzuki
Resetting the array. Current: suzuki
