This article mainly introduces the usage of ftp_chdir and ftp_cdup functions in php, describes the FTP directory operation skills in PHP in the form of examples, and has some reference value, for more information about ftp_chdir and ftp_cdup functions in php, see the example below. Share it with you for your reference. The usage is as follows:

If the switch succeeds, true is returned. otherwise, false is returned. if the switch fails, php will issue a warning.
