Links in PHP and HTML
A growing reference for myself as much as anyone else :)
Relative to site root
Include statements in PHP files:
Links in HTML elements, including links, stylesheets, scripts, and images:
// Yes! The leading / refers to the site root <a href="/mypage.php">My Link</a> // NO! // This can end up with a link like 'C:server/htdocs/mypage.php', which is "correct" // but won't execute. <a href=<?php echo $_SERVER["DOCUMENT_ROOT"]."/mypage.php"?>>My Link</a>
Relative to Current Page
Good news! They work the same way!
// in current directory include_once "file.php"; <a href="mypage.php">My Link</a> // in a parent folder include_once "../file.php"; <a href="../mypage.php">My Link</a> // in a child folder include_once "folder/file.php"; <a href="folder/mypage.php">My Link</a>
Other things that may be situationally useful
You can set a base URL to use for all relative links in HTML elements on a page.
