class PhpLexer(RegexLexer):
    """
    For `PHP <http://www.php.net/>`_ source code.
    For PHP embedded in HTML, use the `HtmlPhpLexer`.

    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.
