RarEntry::extract

(PECL rar >= 0.1)

RarEntry::extractExtract entry from the archive

Descrição

public bool RarEntry::extract ( string $dir [, string $filepath = '' [, string $password = NULL [, bool $extended_data = false ]]] )

RarEntry::extract() extracts the entry's data. It will create new file in the specified dir with the name identical to the entry's name, unless the second argument is specified. See below for more information.

Parâmetros

dir

Path to the directory where files should be extracted. This parameter is considered if and only if filepath is not. If both parameters are empty an extraction to the current directory will be attempted.

filepath

Path (relative or absolute) containing the directory and filename of the extracted file. This parameter overrides both the parameter dir and the original file name.

password

The password used to encrypt this entry. If the entry is not encrypted, this value will not be used and can be omitted. If this parameter is omitted and the entry is encrypted, the password given to rar_open(), if any, will be used. If a wrong password is given, either explicitly or implicitly via rar_open(), CRC checking will fail and this method will fail and return FALSE. If no password is given and one is required, this method will fail and return FALSE. You can check whether an entry is encrypted with RarEntry::isEncrypted().

extended_data

If TRUE, extended information such as NTFS ACLs and Unix owner information will be set in the extract files, as long as it's present in the archive.

Aviso

Prior to version 2.0.0, this function would not handle relative paths correctly. Use realpath() as a workaround.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em caso de falha.

Changelog

Versão Descrição
3.0.0 extended_data was added.
3.0.0 Support for RAR archives with repeated entry names is no longer defective.

If the entry to extract is a directory as per RarEntry::isDirectory(), this method does not seem to extract the entries below that directory as one might expect from using the command-line RAR or WinRAR.
