<methodname>RarEntry::extract</methodname> extracts the entry's data.
It will create new file in the specified

unless the second argument is specified. See below for more information.

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

<para>
Path (relative or absolute) containing the directory and filename of the

<para>
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
<function>rar_open</function>, if any, will be used. If a wrong password is given, either explicitly
or implicitly via <function>rar_open</function>, 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 <methodname>RarEntry::isEncrypted</methodname>.
