# BaseUrl Helper

While most URLs generated by the framework have the base URL prepended automatically, developers will need to prepend the base URL to their own URLs in order for paths to resources to be correct.

Usage of the BaseUrl helper is very straightforward:

    /*
     * The following assume that the base URL of the page/application is "/mypage".
     */

    /*
     * Prints:
     * <base href="/mypage/" />
     */
    <base href="<?php echo $this->baseUrl(); ?>" />

    /*
     * Prints:
     * <link rel="stylesheet" type="text/css" href="/mypage/css/base.css" />
     */
    <link rel="stylesheet" type="text/css"
         href="<?php echo $this->baseUrl('css/base.css'); ?>" />

For simplicity's sake, we strip out the entry PHP file (e.g., "`index.php`") from the base URL that was contained in `Zend_Controller`. However, in some situations this may cause a problem. If one occurs, use `$this->getHelper('BaseUrl')->setBaseUrl()` to set your own BaseUrl.
