Archive_Tar::extractModify() -- extract files to a new dir

Description

This method extracts all the content of the archive in the directory indicated by path. When relevant the memorized path of the files or directories can be modified by removing the remove_path path at the beginning of the file or directory path.

While extracting a file: If the file already exists it is replaced without looking for last modification date. If the file already exists and is write protected, the extraction is aborted. If a directory with the same name already exists, the extraction is aborted.

While extracting a directory, if a file with the same name already exists, the extraction is aborted. While extracting a file/directory if the destination directory exist and is write protected, or does not exist but can not be created, the extraction is aborted. If after extraction an extracted file does not show the correct stored file size, the extraction is aborted.

Parameter

  • string $path - the path of the directory where the files and/or directories need to by extracted.

  • string $remove_path - part of the memorized path that can be removed if present at the beginning of the files or directories path.
