this function gives you a listing of either the files / directories / both or an unformated array (like the PHP function ftp_rawlist()).
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 $mode = NET_FTP_DIRS_FILES] - A constant representing the nodes list (directories, files, both or a ram directory listing). This parameter is determined by the constants (see: Constants). This parameter is optional and will be set for listing directories and files structured in an array.
mixed - a directory listing in the form you determine on success, otherwise PEAR::Error.
Several errors may be returned by ls. The errornumber is unspecific (until now) and will not tell you anything about the errormessage. Possible errors are:
Table 54-1. Possible PEAR_Error values
|Raw directory-list in wrong format.||The format given by the server on PHP function ftp_rawlist()was wrong. Check if the directory you wanted to be listed is correct and you have access to listing it.||Specify a correct directory path (eg. /my/file/path/, ../) and check (maybe change) the rights on it.|
|Could not get last-modification-date of '$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.||
|Date-format failed on timestamp '$res'.||The given format-string was not well formated.||Check the documentation of the PHP function date().|
