    Here’s a short explanation of the configuration
    directives.

    filter.default string

    Filter all $_GET, $_POST, $_COOKIE, $_REQUEST and $_SERVER data by this filter. Original
    data can be accessed through filter_input().

    Accepts the name of the filter you like to use by
    default. See the existing filter list for the list of the filter names.

    Note:

    Be careful about the default flags for the default
    filters. You should explicitly set them to the value you want. For
    example, to configure the default filter to behave exactly like
    htmlspecialchars() you need to set them
    default flags to 0 as shown below.

    Example #1 Configuring the default filter to act like
    htmlspecialchars

    filter.default = full_special_chars
    filter.default_flags = 0
    filter.default_flags integer

    Default flags to apply when the default filter is
    set. This is set to
    FILTER_FLAG_NO_ENCODE_QUOTES by
    default for backwards compatibility reasons. See the flag list for the list
    of all the flag names.
