PHP Begin checking for events and calling callbacks for the default loop

说明

final public static void Ev::run ([ int $flags ] )

Begin checking for events and calling callbacks for the default loop . Returns when a callback calls Ev::stop() method, or the flags are nonzero(in which case the return value is true) or when there are no active watchers which reference the loop( EvWatcher::keepalive() is TRUE), in which case the return value will be FALSE. The return value can generally be interpreted as if TRUE, there is more work left to do .
