public function Archive_Tar::createModify

This method creates the archive file and add the files / directories that are listed in $p_filelist. If the file already exists and is writable, it is replaced by the new tar. It is a create and not an add. If the file exists and is read-only or is a directory it is not replaced. The method return false and a PEAR error text. 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. See also addModify() method for file adding properties.
