PharData::extractTo — Extract the contents of a tar/zip archive to a directory
Beschreibung
$directory, array|string|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().

Anmerkungen
Hinweis:
Windows NTFS-Dateisysteme unterstützen einige Zeichen in Dateinamen nicht, nämlich
<|>*?":. Dateinamen mit einem Punkt am Ende werden ebenfalls nicht unterstützt. Im Gegensatz zu einigen Extraktionswerkzeugen ersetzt diese Methode diese Zeichen nicht durch einen Unterstrich, sondern extrahiert solche Dateien nicht.
