PharData::extractTo — Extract the contents of a tar/zip archive to a directory

说明

public PharData::extractTo ( string $pathto , string|array|null $files = null , bool $overwrite = false ) : bool

Extract all files within a tar/zip archive to disk. Extracted files and directories preserve permissions as stored in the archive. The optional parameters allow optional control over which files are extracted, and whether existing files on disk can be overwritten. The second parameter files can be either the name of a file or directory to extract, or an array of names of files and directories to extract. By default, this method will not overwrite existing files, the third parameter can be set to true to enable overwriting of files. This method is similar to ZipArchive::extractTo().
