Workerman是一個(gè)高性能的PHP Socket服務(wù)器框架，用于構(gòu)建高并發(fā)應(yīng)用。在Workerman中處理異常主要涉及到兩個(gè)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(yǔ)句來(lái)捕獲異常。當(dāng)在處理客戶(hù)端請(qǐng)求時(shí)發(fā)生異常，你可以捕獲異常并進(jìn)行相應(yīng)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(hù)端請(qǐng)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();
  1. 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(diào)試。你可以使用PHP的內(nèi)置函數(shù)error_log()來(lái)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(hù)端請(qǐng)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(gè)示例中，當(dāng)捕獲到ServerException異常時(shí)，我們將異常信息記錄到了指定的日志文件中。你可以根據(jù)需要調(diào)整日志級(jí)別和日志文件路徑。
