Could not connect to server when node.js/socket.io not start. Please make is connected to check. about elephant.io HOT 7 CLOSED

@ve3 We can catch to exception about server connection failure.
I think that isConnect was not needed.

When you used code like next, you would catch to exception to server connection failure.

<?php
use ElephantIO\Client,
    ElephantIO\Engine\SocketIO\Version1X,
    ElephantIO\Exception\ServerConnectionFailureException;

require __DIR__ . '/../../../../vendor/autoload.php';

$client = new Client(new Version1X('http://localhost:1337'));

try
{
    $client->initialize();
    $client->emit('broadcast', ['foo' => 'bar']);
    $client->close();
}
catch (ServerConnectionFailureException $e)
{
    echo 'Server Connection Failure!!';
}

@kbu1564 No, I cannot use try catch.
I was tried this before but the Elephant.IO throw the error before it pass to catch the error. That's why i need isConnected() method.

@ve3 I think that you were not used to namespace of ElephantIO\Exception\ServerConnectionFailureException.

If you were not used about namespace, you can modify like next. :)

<?php
use ElephantIO\Exception\ServerConnectionFailureException;

$client = new \ElephantIO\Client(new \ElephantIO\Engine\SocketIO\Version1X('http://localhost:1337'));

try
{
    $client->initialize();
    $client->emit('broadcast', ['foo' => 'bar']);
    $client->close();
}
catch (ServerConnectionFailureException $e)
{
    echo 'Server Connection Failure!!';
}

I was tried that exactly you said and i was tried more than twice but It did not work.
"An error occurred while trying to establish a connection to the server"
This error was throw before it can catch

Please try it yourself first.

You cannot prevent thrown error (http://stackoverflow.com/questions/8835004/php-throw-exception-is-caught-but-the-error-message-still-appear).

I just want to use socket.io as optional, that's why when it is not connected I want it just pass without throwing the error.
And that's why i needs isConnected. There is no other way to do this except making something to check the connection.

As @kbu1564 said, this exception occurs only on the handshake... which is catchable. When using write, a check is made to check if the connection is made, and does nothing it the connection is not active. The try catch should do the trick (we're using it just fine here at Wisembly, with the dialog being optionnal)

I don't really see the point for a isConnected method...

Ok, I found the point of this problem now, thank you all.
