Php-rpc

Small library to provide remote proceedure calls in PHP over System V on Linux.

Installation

Currently the project contains only one file. Simply add it to your project.

The following methods are use to invoke an RPC

    rpc( $funcName, ...$params );
    rpc_listen( &$caller_id, &$msgArr, $bBlock = true );
    rpc_reply( $caller_id, $obj );

rpc( $funcName, ...$params )

Invoke a remote proceedure call. All parameters are serialized and sent to
the server. The call blocks until the results are returned.

rpc_listen( &$caller_id, &$msgArr, $bBlock = true );

The server must periodically call rpc_listen(). This call will populate the
array &msgArr and $caller_id according to what message has been retrieved from
the queue. The array &msgArr might contain other client messages which have only partially been
recieved. The array must be used on subsequent calls to rpc_listen if it is not empty.

The unserialized object is returned.

rpc_reply( $caller_id, $obj );

This call must be invoked after the rpc instructions have been completed by the server. It is up to the
server implementation whether or not these calls invoke a 'real' PHP function or something else. The call
must pass back the results of the RPC in $obj. These will be serialized to back to the client. Note that
the client is blocking on this call.
