Reference Types

In PHP, it is possible to pass variables by reference. In Python, this can be achieved by wrapping the variable in a phpy.Reference object.

Example

import phpy

errno = phpy.Reference()
errstr = phpy.Reference()
rs = phpy.call("stream_socket_client", 'tcp://127.0.0.1:9999', errno, errstr, 30)
