Current Directory

This function changes the current working directory to that given by the argument. If path is null or empty, the change will be to the user's home directory. A tilde character (`~') appearing in path is expanded to the user's home directory as in a Unix shell. The return value is 1 if the change succeeds, 0 otherwise.

(string) Pwd()
This function returns a string containing the absolute path to the current directory.
