note 110945 added to amqpqueue.consume

Be careful using this function with non-zero amqp.timeout (you may check at AMQPConnection::getTimeout), because it looks like timeout value says how long to wait for a new message from broker before die in way like Fatal error: Uncaught exception 'AMQPConnectionException' with message 'Resource temporarily unavailable' in /path/to/your/file.php:12 Stack trace: #0 /path/to/your/file.php(12): AMQPQueue->consume(Object(Closure), 128) #1 {main} thrown in /path/to/your/file.php on line 12 As for notes about blocking, system resources greediness and so and so, you can investigate how it works by looking in amqp_queue.c for read_message_from_channel C function declaration and PHP_METHOD(amqp_queue_class, consume) method declaration. For me it works perfectly without any uncommon resources usage or I/O performance degradation under the load of 10k 64b message per second with delivery time for less than 0.001 sec.

To exit this consumption loop your callback function or method (i prefer to use closures, btw) should return FALSE. The benefit of this function is that you don't have manually iteration for all messages, and what is more important, if there is no unprocessed messages in queue it will wait for such for you. So you have just to run you consumer (one or many) and optionally time to time check whether they still alive just for reason if you are not sure about callbacks or memory-limit-critical stuff ---- Server IP: 69.147.83.199 Probable Submitter: 92.244.100.226 ---- Manual Page -- http://php.net/manual/en/amqpqueue.consume.php Edit -- https://master.php.net/note/edit/110945 Del: integrated -- https://master.php.net/note/delete/110945/integrated Del: useless -- https://master.php.net/note/delete/110945/useless Del: bad code -- https://master.php.net/note/delete/110945/bad+code Del: spam -- https://master.php.net/note/delete/110945/spam Del: non-english -- https://master.php.net/note/delete/110945/non-english Del: in docs -- https://master.php.net/note/delete/110945/in+docs Del: other reasons-- https://master.php.net/note/delete/110945 Reject -- https://master.php.net/note/reject/110945 Search -- https://master.php.net/manage/user-notes.php
