Throws
Several errors may be returned by mdtm. The errornumber is unspecific (until now) and will not tell you anything about the errormessage. Possible errors are:
The filename you gave the method does not reference a regular-file but a directory.
Specify a correct filenamepath (eg. /my/file/path/foo.html, ../foo.html).
Could not get last-modification-date of '$file'.
The last-modification date could not be determined by PHP. Reasons for this may be that your FTP-server does not support the used command or that you gave the function a non existent file as reference.
check the given file for existence
contact the FTP server's admin
Date-format failed on timestamp '$res'.
The given format-string was not well formated.
Check the documentation of the PHP function date().
<?php var_dump($test->mdtm('/foo/bar')); // returns the last modification time in german timeformat var_dump($test->mdtm('/foo/bar', 'd.m.Y, H:i')); ?>
