AMQPQueue::get

(PECL amqp >= Unknown)

AMQPQueue::get — Retrieve the next message from the queue.

说明

public mixed AMQPQueue::get ([ int $flags = ini_get("amqp.auto_ack") ] )

Retrieve the next available message from the queue. If no messages are present in the queue, this function will return FALSE immediately. This is a non blocking alternative to the AMQPQueue::consume() method.

Currently, the only supported flag for the flags parameter is AMQP_AUTOACK. If this flag is passed in, then the message returned will automatically be marked as acknowledged by the broker as soon as the frames are sent to the client.

参数

flags: A bitmask of supported flags for the method call. Currently, the only the supported flag is AMQP_AUTOACK. If this value is not provided, it will use the value of amqp.auto_ack.

返回值

An instance of AMQPEnvelope representing the message pulled from the queue, or FALSE.
