php workman怎样处理异常

Workerman是一个高性能的PHP Socket服务器框架，用于构建高并发应用。在Workerman中处理异常主要涉及到两个方面：捕获异常和记录日志。

1. 捕获异常：

在Workerman中，你可以使用try-catch语句来捕获异常。当在处理客户端请求时发生异常，你可以捕获异常并进行相应的处理。例如：

use Workerman\Worker; use Workerman\Exception\ServerException; $worker = new Worker('tcp://0.0.0.0:8080'); $worker->count = 4; $worker->onConnect = function ($connection) { echo "New connection: " . $connection->id . PHP_EOL; }; $worker->onMessage = function ($connection, $data) { try { // 处理客户端请求的逻辑 $response = "Server received: " . $data; } catch (ServerException $e) { // 捕获异常 $response = "Error: " . $e->getMessage(); } $connection->send($response); }; $worker->onClose = function ($connection) { echo "Connection closed: " . $connection->id . PHP_EOL; }; Worker::runAll(); 

2. 记录日志：

在捕获异常后，你可能希望将异常信息记录到日志文件中，以便于分析和调试。你可以使用PHP的内置函数error_log()来记录日志。例如：

use Workerman\Worker; use Workerman\Exception\ServerException; $worker = new Worker('tcp://0.0.0.0:8080'); $worker->count = 4; $worker->onConnect = function ($connection) { echo "New connection: " . $connection->id . PHP_EOL; }; $worker->onMessage = function ($connection, $data) { try { // 处理客户端请求的逻辑 $response = "Server received: " . $data; } catch (ServerException $e) { // 捕获异常 $error_message = "Error: " . $e->getMessage(); // 记录日志 error_log($error_message, 3, '/path/to/your/logfile.log'); $response = "Error: " . $error_message; } $connection->send($response); }; $worker->onClose = function ($connection) { echo "Connection closed: " . $connection->id . PHP_EOL; }; Worker::runAll(); 

在这个示例中，当捕获到ServerException异常时，我们将异常信息记录到了指定的日志文件中。你可以根据需要调整日志级别和日志文件路径。
