this function gives you a listing of either the files / directories / both or an unformated array (like the PHP function ftp_rawlist()).
Parameter
string [$dir = null] - The directory to list. You can either use a relative or an absolute path. This optional parameter will be set to the current path.
int $mode = NET_FTP_DIRS_FILES - A constant representing the nodes list (directories, files, both or a ram directory listing). This parameter is determined by the constants ( see: Constants). This parameter is optional and will be set for listing directories and files structured in an array.
Return value
mixed - a directory listing in the form you determine on success, otherwise PEAR::Error.
Throws
Several errors may be returned by ls. The errornumber is unspecific (until now) and will not tell you anything about the errormessage. Possible errors are:
The format given by the server on PHP function ftp_rawlist()was wrong. Check if the directory you wanted to be listed is correct and you have access to listing it.
Specify a correct directory path (eg. /my/file/path/, ../) and check (maybe change) the rights on it.
Could not get last-modification-date of '$file'.
The last-modification date could not be determined by PHP. Reasons for this might be that your FTP-server does not support the used command or that you gave the function a non existent file as reference.
check the given file for existence
contact the FTP server's admin
Date-format failed on timestamp '$res'.
The given format-string was not well formated.
Check the documentation of the PHP function date().
