echo 'My current working directory is '.posix_getcwd();
?>

注释

Note:

This function can fail on

• Read or Search permission was denied

From the GNU getcwd(3) manpage, paraphrased: returns the absolute pathname of the current working directory. Fails when the current directory is not eradable. Complies with POSIX.1 spec.
