PHP 通過 AMQP 庫使用 RabbitMQ 的簡單示例Demo

測試步驟和項目結構

測試步驟

安裝 RabbitMQ 和 PHP 的步驟就不在這裏說了。測試步驟如下：

1. 創建測試項目的目錄 mq
2. 從 https://github.com/php-amqplib/php-amqplib 下載AMQP庫（當然也可以通過 composer 安裝，這裏爲了簡單直接自己處理了），放入 mq 目錄
3. 編寫 index.php，實現自動加載
4. 創建 test 目錄，裏面分別創建 mqc.php 消費者和 mqp.php 生產者兩個文件
5. 跑腳本，測試消息的生產和消費：
   • php -f index.php mqp 生產消息
   • php -f index.php mqc 消費消息

源碼

index.php

// 調生產者
function mqp() {
	$p = new \test\mqp();
	$p->p();
}


// 調消費者
function mqc() {
	$c = new \test\mqc();
	$c->c();
}


// 取命令行參數，執行對應函數
if (function_exists($argv[1])) {
	$argv[1]();
}

mqc.php

		$channel = $connection->channel();

		$channel->exchange_declare('myExchange', 'direct', false, true, false);
		$channel->queue_declare('myQueue', false, true, false, false);

		//閉包回調函數
