推荐答案

您需要安装实现该功能的PHP posix扩展.如果没有该扩展名，就不会定义该函数，这会导致错误.

You need to install PHP's posix extension which implements that function. Without that extension the function simply is not defined, which leads to the error.

如何安装这样的扩展软件包取决于您的操作系统.最简单的方法是在Linux中，您只需在软件管理系统内单击即可搜索，识别，下载和安装软件包.

How to install such an extension package depends on your operating system. Easiest is in Linux where you can search, identify, download and install packages with a single click inside the software management system.
