How do you get PHP, Symlinks and __FILE__ to work together nicely?

Question

On localhost. I have the following directory structure:

/share/www/trunk/wp-content/plugins/otherfolders

/share/www/portfolio/wp-content/s

Answer 1

Here is the solution to that issue: https://github.com/logical-and/symlink-detective

$root = dirname(dirname(dirname(dirname(__FILE__))));
  if (file_exists(SymlinkDetective::detectPath($root.'/wp-load.php'))) {
      // WP 2.6
      require_once(SymlinkDetective::detectPath($root.'/wp-load.php'));
  }

or you can try that

try {
  $root = dirname(dirname(dirname(dirname(__FILE__))));
  require_once SymlinkDetective::detectPath($root.'/wp-load.php', '', 
    false /* this would throw an exception if file doesn't exists */);
}
catch (Exception $e) {
  // nothing to do if file doesn't exists
}
