More Information More Information
In a Plugin or Theme, it can be used as early as the setup_theme Action. Any earlier usage, including plugins_loaded, generates a Fatal Error.
Note that when used outside The Loop on a posts page (index, archive, etc.) without the ID parameter, it will return the URL of the last post in The Loop, not the permalink for the current page.
