    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``.

    `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
