swoole error handling method

#You can directly use try/catch to handle exceptions in coroutine programming. However, exceptions must be caught within the coroutine and cannot be caught across coroutines.

Not only the Exception thrown by the application layer, but also some errors at the bottom level can also be captured, such as function, class, method does not exist

Error

In the following code, try/catch and throw are in different coroutines, and this exception cannot be caught within the coroutine. When the coroutine exits, an uncaught exception is found, which will cause a fatal error.

Fatal error: Uncaught RuntimeException

try {
    Swoole\Coroutine::create(function () {
        throw new \RuntimeException(__FILE__, __LINE__);
    });
}
catch (\Throwable $e) {
    echo $e;
}

Correct

Catch exceptions within the coroutine.

function test() {
    throw new \RuntimeException(__FILE__, __LINE__);
}

Swoole\Coroutine::create(function () {
    try {
        test();
    }
    catch (\Throwable $e) {
        echo $e;
    }
});
