Usage

First, you need to create a database for storing a message queue on MySQL server.

CREATE TABLE myqueue (
  `id`           BIGINT UNSIGNED NOT NULL AUTO_INCREMENT,
  `locked_until` TIMESTAMP NOT NULL DEFAULT "0000-00-00 00:00:00",
  `data`         BLOB NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB;

You can change the name of the table (myqueue) as you like.

Then, here is an example code of using MyQueue class.

require_once 'MyQueue.php';
$pdo = new PDO('mysql:host=127.0.0.1;dbname=test');
$queue = new MyQueue($pdo, 'myqueue');
$queue->push('message1');
$queue->push('message2');
$queue->push('message3');
$queue->pop();  // => 'message1'
$queue->pop();  // => 'message2'
$queue->pop();  // => 'message3'

To run this code, you need MySQL server running on localhost, and it must have test database.

If you changed the name of the table, you have to change 'myqueue' in the source code to your table name.
