CLII. Standard PHP Library (SPL) Functions
Introduzione
SPL is a collection of interfaces and classes that are meant to solve standard problems.
Suggerimento: A more detailed documentation of SPL can be found here.
Installazione
This extension is available and compiled by default in PHP 5.
Costanti predefinite
Queste costanti sono definite da questa estensione e sono disponibili solo se l'estensione è stata compilata nel PHP o se è stata caricata dinamicamente a runtime.
| Avvertimento |
SPL uses class constants since PHP 5.1. Prior releases use global constants in the form RIT_LEAVES_ONLY. |
