44 * 1) If $target is a Title, the correct URL to link to will be figured
46 * 2) It automatically adds the usual classes for various types of link
47 * targets: "new" for red links, "stub" for short articles, etc.
48 * 3) It escapes all attribute values safely so there's no risk of XSS.
49 * 4) It provides a default tooltip if the target is a Title (the page
50 * name of the target).
51 * link() replaces the old functions in the makeLink() family.
53 * @since 1.18 Method exists since 1.16 as non-static, made static in 1.18.
54 * @deprecated since 1.28, use MediaWiki\Linker\LinkRenderer instead
56 * @param LinkTarget $target Can currently only be a LinkTarget, but this may
57 * change to support Images, literal URLs, etc.
58 * @param string $html The HTML contents of the <a> element, i.e.,
59 * the link text. This is raw HTML and will not be escaped. If null,
60 * defaults to the prefixed text of the Title; or if the Title is just a
61 * fragment, the contents of the fragment.
62 * @param array $customAttribs A key => value array of extra HTML attributes,
63 * such as title and class. (href is ignored.) Classes will be
64 * merged with the default classes, while other attributes will replace
65 * default attributes. All passed attribute values will be HTML-escaped.
66 * A false attribute value means to suppress that attribute.
67 * @param array $query The query string to append to the URL
68 * you're linking to, in key => value array form. Query keys and values
69 * will be URL-encoded.
70 * @param string|array $options String or array of strings:
71 * 'known': Page is known to exist, so don't check if it does.
72 * 'broken': Page is known not to exist, so don't check if it does.
73 * 'noclasses': Don't add any classes automatically (includes "new",
74 * "stub", "mw-redirect", "extiw"). Only use the class attribute
75 * provided, if any, so you get a simple blue link with no funny i-
77 * 'forcearticlepath': Use the article path always, even with a querystring.
78 * Has compatibility issues on some setups, so avoid wherever possible.
79 * 'http': Force a full URL with http:// as the scheme.
80 * 'https': Force a full URL with https:// as the scheme.
