This child process will correctly change dirs as directed, but the current directory of the parent process - your PHP script execution - remains unchanged. The chdir() function is executed by the PHP engine, and changes the working directory of your PHP process. -- >O Ernest E. Vogelsinger (\) ICQ #13394035 ^ http://www.vogelsinger.at/
