可先回避一下
socket_select($r = array($this->socket), $w = NULL, $f = NULL, $to_sec, $to_usec)
写作
@socket_select($r = array($this->socket), $w = NULL, $f = NULL, $to_sec, $to_usec)
也可以 error_reporting(E_ALL ^ E_STRICT); 一下
由原型
int socket_select ( array &read, array &write, array &except, int tv_sec [, int tv_usec] )
可知，前三个参数是引用传递的
从 php5.3 起，引用必须产生于实体，否则就会报错
并不排除以后会联回避都不行了
正确的写法是
$r = array($this->socket);
$w = NULL;
$f = NULL;
socket_select($r, $w, $f, $to_sec, $to_usec)
??板大，
??已?解?了，
感恩！
