Why code is checking if $this->connectionHandler is_array?

[adrianharabula]

Hello,

I was looking over the following code

php-multithreaded-socket-server/sock/SocketServer.php

Lines 79 to 87 in e23c3f1

	if( is_array( $this->connectionHandler ) ) {
	$object = $this->connectionHandler[0];
	$method = $this->connectionHandler[1];
	$object->$method( $socketClient );
	}
	else {
	$function = $this->connectionHandler;
	$function( $socketClient );
	}

And was asking why is not just

$function = $this->connectionHandler;
$function( $socketClient );

Can you give an example of a connectionHandler passed as an array?

Thanks!
