Additional options accepted:
`startinline`
If given and ``True`` the lexer starts highlighting with
php code (i.e.: no starting ``<?php`` required). The default
is ``False``.
`funcnamehighlighting`
If given and ``True``, highlight builtin function names
(default: ``True``).
`disabledmodules`
If given, must be a list of module names whose function names
should not be highlighted. By default all modules are highlighted
except the special ``'unknown'`` module that includes functions
that are known to php but are undocumented.
To get a list of allowed modules have a look into the
`_php_builtins` module:
.. sourcecode:: pycon
>>> from pygments.lexers._php_builtins import MODULES
>>> MODULES.keys()
['PHP Options/Info', 'Zip', 'dba', ...]
In fact the names of those modules match the module names from
the php documentation.
