OK, I understand. AFAIK, there's no way to do that in PHP without writing an extension in C, is there?<div><div></div><div><br><br><br><div class="gmail_quote">On Wed, Jun 29, 2011 at 2:47 PM, Gavin M.

Thanks for the work on amqphp, will look deeper at it for use in other areas. I'm glad there is an active, maintained client!</div>

BTW, Gavin, on this point:<div><br><br>> iirc the existing implementations do not have connection pooling<br><br></div>I've recently updated amqphp so that you can manage multiple connections at the same time, so for example you can connect to and consume from 2 or more different brokers at the same time. There's a demo here:<br>

While not directly related to your question and you've not specified your use case, I have found trying to use native AMQP drivers in my PHP application as having too much overhead for connection management and iirc the existing implementations do not have connection pooling. This means lots of startup time and overhead on every request. To get around this we created a HTTP library that talks to the RabbitMQ JSON RPC Channel plugin. If all you are doing is publishing, you might want to check out VorpalBunny:<br>

As far as the underlying implementation, it's worth noting that the rabbitmq-c library is considered experimental. While we use it in our C applications in production, I can't say that we use the PHP extension on top of it. The PHP site has fatal errors for me right now so I can't look up to see which PHP extension the code is based on, otherwise I'd poke into the code and let you know if there are any timeout settings.<br>
