Such debugger exists, but it isn't part of the language itself. It's
composed of two parts:

1. A server-side library you plug into your PHP installation
2. A client-side tool to interact with the first component

.... and there are several alternatives to choose for.

For #1, the most common option is Xdebug, probably because it's the only
decent free tool out there (all other tools I know are proprietary and
cost money). It's reasonably good, but you must be sure you follow the
official documentation if you want to configure it: docs you find out
there tend to be pretty outdated.

For #2, you need a tool that's compatible with your first choice. As far
as I know, most IDEs (but not all) support Xdebug: NetBeans IDE,
Exclipse, PhpStorm, Komodo IDE...

Some IDEs force you to use their own Apache+PHP+Xdebug bundle, which can
make things more difficult to understand.

Additionally, there're browser extensions for Firefox, Chrome, Opera...
that simplify enabling and disabling debugging.
