Dodatek I. Lista aliasów funkcji
W PHP jest wiele funkcji, które można wywołać poprzez więcej niż jedną nazwę. W niektórych przypadkach nie ma preferowanej nazwy, na przykład is_int() i is_integer() są sobie równoważne pod każdym względem. Jednakże istnieją także funkcje, których nazwy się zmieniły z powodu czyszczenia API lub kompatybilności wstecznej. Zazwyczaj źle jest używać takich aliasów, jako że może to prowadzić do uzależnienia funkcjonowania skryptu od wersji PHP. Ta lista przeznaczona jest dla osób, które chcą uaktualnić swoje stare skrypty do nowej składni.
Ta lista jest zgodna z PHP 4.0.6. Listę aliasów aktualizowaną codzinnie można znaleźć pod adresem http://zend.com/phpfunc/all_aliases.php.

| Description of core php.ini directives | Początek rozdziału | List of Reserved Words |
Język PHP to dzisiaj powszechnie przyjęty standard, podstawa tworzenia dynamicznych stron WWW, opartych na bazach danych.
PHP to język skryptowy. Znaczy to, że jest to język nie kompilowalny. Program jest wykonywany przez interpreter na podstawie jego kodu źródłowego. Język PHP to element technologii internetowej SERVER-SIDE. Znaczy to, że kod języka jest wykonywany od strony serwera (na serwerze).
W jakim celu używac PHP? Po co to komu?
Załóżmy, że potrzebujemy takiej strony internetowej, która wyświetli zawsze bieżącą datę. Dzięki technologii PHP, datę i godzinę odczytywać można z miejsca gdzie wykonuje się skrypt, np. gdy serwer znajduje się w USA a my w Polsce to widoczna jest różnica w czasie który zostanie wyświetlony.
