LXXXIX. OpenAL Audio Bindings

简介

Platform independent audio bindings. Requires the OpenAL library.

安装

PECL 扩展未绑定于 PHP 中。

进一步信息例如新版本,下载,源程序,维护者信息以及更新日志可以在此找到: http://pecl.php.net/package/openal.

可以从 PHP 下载页面或者 http://snaps.php.net/ 下载此 PECL 扩展的 DLL 文件。

运行时配置

本扩展模块在 php.ini 中未定义任何设置指令。

资源类型

This extension defines four resource types: Open AL(Device) - Returned by openal_device_open(), Open AL(Context) - Returned by openal_context_create(), Open AL(Buffer) - Returned by openal_buffer_create(), and Open AL(Source) - Returned by openal_source_create().
