#UNZIPPER PHP RAR#
i have no problem with the unzipper in zipping and unzipping feature, but with the rar functionality You are receiving this because you commented. $filesecta = explode("\x50\x4b\x03\x04", $filesecta) Īrray_shift($filesecta) // Removes empty entry/signature Alternatively, ask if you are using a version of php that is, or more than 5.6 as it comes with this versions by default. Cut entries from the central directory The best part: Unzipper is completely FREE.
Unzipper can open compressed files or compress files. $this->comment = substr($filesecta, 18, $unpackeda) Unzipper is a file archiver just like WinZip or WinRAR. $unpackeda = unpack('x16/v1length', $filesecta) Just an example (not written by me): datasec = array()
#UNZIPPER PHP INSTALL#
If you can't install ZZIPLib, you could use a zip class alternative.
You need to use the ZZIPlib library and the -with-zip= option when compiling php. Zip support in PHP is not enabled by default.
