>本教程概述了如何从Workerman应用程序中与MySQL数据库有效互动。 Workerman本身并未直接处理数据库连接;您需要使用MySQLI或PDO等PHP数据库库。 关键是有效地管理连接,以避免瓶颈和性能问题,尤其是在高分子下。 我们将重点介绍使用连接池有效地管理数据库连接。
>>>有效地将Workerman连接到MySQL数据库>将工作人员连接到MySQL数据库的最有效方法是利用连接池。 连接池预先建立一组数据库连接,最大程度地减少为每个请求创建新连接的开销。这大大提高了性能,尤其是在重负荷下。 这是您可以使用MySqli:<?php class DatabasePool { private $connections = []; private $config = []; private $maxConnections = 10; // Adjust as needed public function __construct($config) { $this->config = $config; } public function getConnection() { if (count($this->connections) < $this->maxConnections) { $this->connections[] = new mysqli( $this->config['host'], $this->config['user'], $this->config['password'], $this->config['database'] ); if ($this->connections[count($this->connections)-1]->connect_errno) { die("Failed to connect to MySQL: " . $this->connections[count($this->connections)-1]->connect_error); } } return array_shift($this->connections); } public function releaseConnection($connection) { $this->connections[] = $connection; } } // Example usage within your Workerman application: $dbConfig = [ 'host' => 'localhost', 'user' => 'your_username', 'password' => 'your_password', 'database' => 'your_database' ]; $dbPool = new DatabasePool($dbConfig); $conn = $dbPool->getConnection(); // Perform database operations using $conn $dbPool->releaseConnection($conn); ?>

<?php class DatabasePool { private $connections = []; private $config = []; private $maxConnections = 10; // Adjust as needed public function __construct($config) { $this->config = $config; } public function getConnection() { if (count($this->connections) < $this->maxConnections) { $this->connections[] = new mysqli( $this->config['host'], $this->config['user'], $this->config['password'], $this->config['database'] ); if ($this->connections[count($this->connections)-1]->connect_errno) { die("Failed to connect to MySQL: " . $this->connections[count($this->connections)-1]->connect_error); } } return array_shift($this->connections); } public function releaseConnection($connection) { $this->connections[] = $connection; } } // Example usage within your Workerman application: $dbConfig = [ 'host' => 'localhost', 'user' => 'your_username', 'password' => 'your_password', 'database' => 'your_database' ]; $dbPool = new DatabasePool($dbConfig); $conn = $dbPool->getConnection(); // Perform database operations using $conn $dbPool->releaseConnection($conn); ?>
此示例显示了如何使用准备好的语句安全查询数据库。 至关重要的是,请注意,在查询中使用$username
