-## `getHtml()`
+## `getHtml(int $flags = INFO_ALL): string`
 The `getHtml()` method returns the `phpinfo()` output, without the HTML `head` and `body` elements, wrapped in `<div id="phpinfo">` & `</div>`.

+All inline CSS will be "externalized" to CSS classes, you can load `src/assets/info.css` to get the colors back (or `vendor/spaze/phpinfo/src/assets/info.css` when installed via Composer).
 
 An example usage with Nette Framework (can be used with other frameworks or standalone, too):
 ```php
 $this->template->phpinfo = Html::el()->setHtml($this->phpInfo->getHtml());
 ```
 
+The output may be customized by passing one or more of the constants [specified in the PHP manual](https://www.php.net/function.phpinfo#refsect1-function.phpinfo-parameters) in the optional `$flags` parameter.

 Please note that this will also remove the HTML `head` element which contains `meta name="ROBOTS"` tag preventing search engines and other bots indexing the `phpinfo()` output.
 You have to add it back somehow, for example by rendering the `getHtml()` output in your own layout which includes the `head` element with the `meta name="ROBOTS"` tag.
 In general, `phpinfo()` output should be accessible only for authenticated users.

 Sometimes, you may want to display the classic `phpinfo()` output, with the original HTML `head` and `body` elements, `meta name="ROBOTS"` tag, inline styles etc.,
 but still with the sensitive info sanitized (see below). In that case, you may use `getFullPageHtml()`:

 ## Sanitization
 By default, session id will be automatically determined and replaced by `[***]` in the output.
 This is to prevent some session hijacking attacks that would read the session id from the cookie value reflected in the `phpinfo()` output
