Commonly accepted methods for documenting PHP source code in auto-dock?

Question

Automatically generate PHP documentation?

I am new to PHP and my current job requires me to quickly raise the language.

I am a document writer. I even like to write documents. I am familiar with the accepted documentation syntax and tools for several languages.

This does not apply to PHP.

I know that there are always several methods for writing source code comments that are available for a document, and there are usually different tools for each language. However, I am in an environment that is not required to have a standard commenting method, as well as a standard PHP autostart tool. This gives me freedom of choice and a little paralysis on analysis to go along with this.

Is phpDocumentor ( http://www.phpdoc.org/ ) an acceptable standard PHP auto-dock tool?

Is it acceptable to follow the general JavaDoc rules for code when documenting PHP code?
