@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环$ Q% {/ n/ @' }
现在socket读写数据的流程是这样的：
" p: c/ E& I" {$ ], s0 Q( ~
5 s* d% m, J: p% g3 \$ k, r J$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

/ j) }" `" U8 J; Z9 \$ L5 e/ N9 Y& @% v6 S/ _9 C
socket_connect($socket, IP, PORT);

socket_write($socket, $strxml, strlen($strxml);/ H8 i. L: A0 D8 z' [2 V
