[UPHPU] Is there any PHP asynchronous messaging solution?

what you are looking for is typically called a MOM (message oriented
middleware). This is a type of system that allows for inter-application or
exter-application communication via some asynchronous method. I doubt you are
going to find anything written in php that will provide the middleware with
features that are you looking for.  if you provide more information on what you
are trying to accomplish i might be able to help you further with some options.

the storage mechanism for message queues can be very different...some are
database and other are implemented in various ways like system memory. you dont
really have much flexibility on this. I dont think i have ever seen one
implemented using mysql...now oracle and db2 i have seen.

since mom protos are not very well defined you will mainly see the sun java
standard of jms. that is the standard for connecting java to a messaging
service. technically, you could probably use any lang if you know how to do it,
however, that might not be what you want to do.

im not sure what your requirements are or what you are trying to accomplish;
however, if you are justing wanted to send messages then i would suggest maybe
taking a simple approach and see if you could use something like jabber with a
mysql backend. then you can access that service via some lang like java (jms) or
something else. If you want a full blown solution, then you can use oracle
queuing or even ibm mq series. However, those are extremely expensive.
