LXXX. OpenAL Audio Bindings

简介

Platform independant audio bindings. Requires the OpenAL library.

安装

This PECL extension is not bundled with PHP.

Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: http://pecl.php.net/package/openal.

You may download this PECL extensions DLL from the PHP Downloads page or at http://snaps.php.net/.

运行时配置

该扩展模块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().

预定义常量

由于这些常量是由该扩展模块定义的，因此只有在该扩展模块被编译到 PHP 中，或者在运行时被动态加载后，这些常量才有效。
