Standard PHP Library (SPL) Functions

简介

SPL is a collection of interfaces and classes that are meant to solve standard problems.

安装

This extension is available and compiled by default in PHP 5.

预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

Warning

SPL uses class constants since PHP 5.1. Prior releases use global constants in the form RIT_LEAVES_ONLY.
