php workman怎樣處理異常

Workerman是一個高性能的PHP Socket服務器框架，用于構建高并發應用。在Workerman中處理異常主要涉及到兩個方面：捕獲異常和記錄日志。

1. 捕獲異常：

在Workerman中，你可以使用try-catch語句來捕獲異常。當在處理客戶端請求時發生異常，你可以捕獲異常并進行相應的處理。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 {
        // 處理客戶端請求的邏輯
        $response = "Server received: " . $data;
    } catch (ServerException $e) {
        // 捕獲異常
        $response = "Error: " . $e->getMessage();
    }
    $connection->send($response);
};

$worker->onClose = function ($connection) {
    echo "Connection closed: " . $connection->id . PHP_EOL;
};

Worker::runAll();

2. 記錄日志：

在捕獲異常后，你可能希望將異常信息記錄到日志文件中，以便于分析和調試。你可以使用PHP的內置函數error_log()來記錄日志。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 {
        // 處理客戶端請求的邏輯
        $response = "Server received: " . $data;
    } catch (ServerException $e) {
        // 捕獲異常
        $error_message = "Error: " . $e->getMessage();
        // 記錄日志
        error_log($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();

在這個示例中，當捕獲到ServerException異常時，我們將異常信息記錄到了指定的日志文件中。你可以根據需要調整日志級別和日志文件路徑。
