PHP语言规范? [英] PHP language specification?

问题描述

我知道有一个Java(JLS)官方文档，我想知道PHP语言是否也是这种情况.我在PHP手册上找到了语言参考"部分，但看起来不像JLS那样详细.

I know there is an official document for Java (JLS), I'd like to know if it's also the case of PHP language. I found the "Language Reference" section on the PHP manual, but it doesn't look as detailed as the JLS.

问题是我对PHP有很好的实践知识，但对于幕后真正发生的事情我一无所知.

The thing is I have a good practical knowledge of PHP but I'm miserably clueless about what really happens under the hood.

如果没有任何官方文件，您能推荐一些好书给我读吗?

If there isn't any official document, could you recommend me some good books to read?

推荐答案

用于PHP语言的初始规范草案现在为

An initial draft specification for the PHP language has now been announced. The introduction of the specification reads as follows:

该规范旨在为PHP语言的语法和语义提供一个完整而简洁的定义，适用于以下人员:

This specification is intended to provide a complete and concise definition of the syntax and semantics of the PHP language, suitable for use by the following:

• PHP编译器的实现者
• PHP语言测试套件的实现者
• 程序员编写PHP代码

目前，已排除运行时库，因为该文档记录在 www.php.net 中.因此，所有对图书馆设施的前向引用都具有形式(§xx)的占位符.

For now, the runtime library has been excluded, as that is documented at www.php.net. As such, all forward references to library facilities have placeholders of the form (§xx).
