However windows will not resolve D:MyFolder as a valid path because a forward/or back slash is omitted after the root drive. The correct path is D:\MyFolder or D:/MyFolder and PHP should be returning false instead of true. Test script: --------------- //change this below to a valid drive and folder but omit the \\ $path = "C:PHP"; assert(is_dir($path) == false); Actual result: -------------- Warning: assert(): Assertion failed ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73758&edit=1
