>本教程概述瞭如何從Workerman應用程序中與MySQL數據庫有效互動。 Workerman本身並未直接處理數據庫連接;您需要使用MySQLI或PDO等PHP數據庫庫。 關鍵是有效地管理連接,以避免瓶頸和性能問題,尤其是在高分子下。 我們將重點介紹使用連接池有效地管理數據庫連接。
>>>有效地將Workerman連接到MySQL數據庫>將工作人員連接到MySQL數據庫的最有效方法是利用連接池。 連接池預先建立一組數據庫連接,最大程度地減少為每個請求創建新連接的開銷。這大大提高了性能,尤其是在重負荷下。 這是您可以使用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); ?>
