158 * 3) It escapes all attribute values safely so there's no risk of XSS.
159 * 4) It provides a default tooltip if the target is a Title (the page
160 * name of the target).
161 * link() replaces the old functions in the makeLink() family.
163 * @since 1.18 Method exists since 1.16 as non-static, made static in 1.18.

166 * $linker->link( ... );
168 * @param $target Title Can currently only be a Title, but this may
169 * change to support Images, literal URLs, etc.
170 * @param $html string The HTML contents of the <a> element, i.e.,
171 * the link text. This is raw HTML and will not be escaped. If null,
172 * defaults to the prefixed text of the Title; or if the Title is just a
173 * fragment, the contents of the fragment.
174 * @param $customAttribs array A key => value array of extra HTML attri-
175 * butes, such as title and class. (href is ignored.) Classes will be
176 * merged with the default classes, while other attributes will replace
177 * default attributes. All passed attribute values will be HTML-escaped.
178 * A false attribute value means to suppress that attribute.
179 * @param $query array The query string to append to the URL
180 * you're linking to, in key => value array form. Query keys and values
181 * will be URL-encoded.
182 * @param $options string|array String or array of strings:
183 * 'known': Page is known to exist, so don't check if it does.
184 * 'broken': Page is known not to exist, so don't check if it does.

186 * "stub", "mw-redirect", "extiw"). Only use the class attribute
187 * provided, if any, so you get a simple blue link with no funny i-
189 * 'forcearticlepath': Use the article path always, even with a querystring.
190 * Has compatibility issues on some setups, so avoid wherever possible.
191 * 'http': Force a full URL with http:// as the scheme.
