简单实用socket

@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

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

6 a3 ?2 W1 x( f0 t! K* Jsocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);

socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
