Another option would be to create a function that converts all slashes in a given input string to whatever the directory seperator should be on that platform. This way, devs wouldn't have to deal with bulky aliases like DIRECTORY_SEPERATOR cluttering up their code. For example: <?php print convert_seperators( '/some\directory/' ); ?> The above would output "/some/directory" on Linux and "\some\directory" on Windows. --Kris
