CXXXIX. Standard PHP Library (SPL) Functions
Introduction
SPL is a collection of interfaces and classes that are meant to solve standard problems.
Tip: A more detailed documentation of SPL can be found here.
Installation
This extension is available and compiled by default in PHP 5.
Predefined Constants
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
