(PECL ev >= 0.2.0)
EvLoop::run — Begin checking for events and calling callbacks for the loop
$flags= 0 ] )
Begin checking for events and calling callbacks for the current event 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 .
flags can be one of the following:
| ||The default behavior described above|
| ||Block at most one(wait, but don't loop)|
| ||Don't block at all(fetch/handle events, but don't wait)|
See the run flag constants .
