gives you the last modification-date of a file either as a unix timestamp or in a formated date.
string $file - The file to check.
string $format - A date()-function styled format-string.
Several errors may be returned by mdtm. The errornumber is unspecific (until now) and will not tell you anything about the errormessage. Possible errors are:
Table 54-1. Possible PEAR_Error values
|Filename '$file' seems to be a directory.||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 '$file'.||The last-modification date could not be determined by PHP. Reasons for this may be that your FTP-server does not support the used command or that you gave the function a non existent file as reference.||
|Date-format failed on timestamp '$res'.||The given format-string was not well formated.||Check the documentation of the PHP function date().|
