|
|
* You can use an array or an anonymous function to provide configuration options:

*
|
|
* - An array will be passed to the `HTMLPurifier_Config::create()` method.
|
|
* - An anonymous function will be called after the config was created.

* instance of `HTMLPurifier_Config`.
|
|
*
|
|
* Here is a usage example of such a function:
|
|
*
|
|
* ```php
|
|
* // Allow the HTML5 data attribute `data-type` on `img` elements.
|
|
* $content = HtmlPurifier::process($content, function ($config) {
|
|
* $config->getHTMLDefinition(true)
|
|
* ->addAttribute('img', 'data-type', 'Text');
|
|
* });
|
|
* ```
|
|
*
|
|
* @return string the purified HTML content.
