`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.

  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.

  ### Configuring the default filter to act like htmlspecialchars

      filter.default = full_special_chars
      filter.default_flags = 0

`filter.default_flags` `int`

- 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.
