  5. 5. Use php 5.3*Use php-amqplib, a php implementation ofamqp protocol fromhttps://github.com/videlalvaro/php-amqplib$ git clone git://github.com/videlalvaro/php-amqplib.gituse composer to resolve depencies$ curl --silent https://getcomposer.org/installer | php$ php composer.phar install* this version of lib require php 5.3 because it use namespaces feature for use it on php 5.2 checkoutfrom http://code.google.com/p/php-amqplib/ and use require_once instead of namespaces
  6. 6. Example:I have a process that execute two operation:1. Download and process some data (fast)2. Download image from web (slow)I dont want to wait for second operation,because its slow!I delegate the second operation to RabbitMQ
  7. 7. Solve with RabbitMQStandard RabbitMQ init init download data download data Queue download images processing data processing data end end C Consumer: consumes the queued data "Processing data" step insert link in queue It will be disposed of by the consumer regardless
  8. 8. Publisher Connection + Channel for AMQP Fast operation, run directly Put (publish) in Queue link for download image
  9. 9. Consumer Connection + Channel for AMQP Process function (download images) this is a callback function used by basic_consume method for queue consume * When the process is completed consumer return an acknowledge to publisher *
