public function Archive_Tar::addModify

This method add the files / directories listed in $p_filelist at the end of the existing archive. If the archive does not yet exists it is created. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. The path indicated in $p_remove_dir will be removed from the memorized path of each file / directory listed when this path exists. By default nothing is removed (empty path '') The path indicated in $p_add_dir will be added at the beginning of the memorized path of each file / directory listed. However it can be set to empty ''. The adding of a path is done after the removing of path. The path add/remove ability enables the user to prepare an archive for extraction in a different path than the origin files are. If a file/dir is already in the archive it will only be added at the end of the archive. There is no update of the existing archived file/dir. However while extracting the archive, the last file will replace the first one. This results in a none optimization of the archive size. If a file/dir does not exist the file/dir is ignored. However an error text is send to PEAR error. If a file/dir is not readable the file/dir is ignored. However an error text is send to PEAR error.

string $p_add_dir A string which contains a path to be: added to the memorized path of each element in the list.

string $p_remove_dir A string which contains a path to be: removed from the memorized path of each element in the list, when relevant.
