| 72 | * purposes: |
| 73 | * 1) If $target is a LinkTarget, the correct URL to link to will be figured |
| 74 | * out automatically. |
| 75 | * 2) It automatically adds the usual classes for various types of link |
| 76 | * targets: "new" for red links, "stub" for short articles, etc. |
| 77 | * 3) It escapes all attribute values safely so there's no risk of XSS. |
| 78 | * 4) It provides a default tooltip if the target is a LinkTarget (the page |
| 79 | * name of the target). |
| 80 | * link() replaces the old functions in the makeLink() family. |
| 81 | * |

| 84 | * |
| 85 | * @param LinkTarget $target Can currently only be a LinkTarget, but this may |
| 86 | * change to support Images, literal URLs, etc. |
| 87 | * @param string|null $html The HTML contents of the <a> element, i.e., |
| 88 | * the link text. This is raw HTML and will not be escaped. If null, |
| 89 | * defaults to the prefixed text of the LinkTarget; or if the LinkTarget is just a |
| 90 | * fragment, the contents of the fragment. |
| 91 | * @param array $customAttribs A key => value array of extra HTML attributes, |
| 92 | * such as title and class. (href is ignored.) Classes will be |
| 93 | * merged with the default classes, while other attributes will replace |
| 94 | * default attributes. All passed attribute values will be HTML-escaped. |
| 95 | * A false attribute value means to suppress that attribute. |
| 96 | * @param array $query The query string to append to the URL |
| 97 | * you're linking to, in key => value array form. Query keys and values |
| 98 | * will be URL-encoded. |
| 99 | * @param string|array $options String or array of strings: |
| 100 | * 'known': Page is known to exist, so don't check if it does. |
| 101 | * 'broken': Page is known not to exist, so don't check if it does. |
| 102 | * 'noclasses': Don't add any classes automatically (includes "new", |
| 103 | * "stub", "mw-redirect", "extiw"). Only use the class attribute |
| 104 | * provided, if any, so you get a simple blue link with no icons. |
| 105 | * 'forcearticlepath': Use the article path always, even with a querystring. |
| 106 | * Has compatibility issues on some setups, so avoid wherever possible. |
| 107 | * 'http': Force a full URL with http:// as the scheme. |
| 108 | * 'https': Force a full URL with https:// as the scheme. |
