boolean PEAR_PackageUpdate::getPackageInfo (
Loads the latest package information from the channel server.
This method contacts the packages channel server using a PEAR_Remote instance. If any errors are encountered (channel server does not host the package, bad package name, etc.) they will be pushed onto the error stack.
Since version 0.5.2, protocol REST 1.0 is also supported. So we try to contact the packages channel server using a PEAR_REST instance, if this channel support the protocol, rather than default protocol XMLRPC.
