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
9 a1 }2 N) [6 _4 P) x现在socket读写数据的流程是这样的：

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

4 T, q( y/ P$ B( n& d5 Q& R( o( Vsocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

: A2 q; n! ^( z% t9 tsocket_connect($socket, IP, PORT);

7 o- r; _& ~8 Y; D  asocket_write($socket, $strxml, strlen($strxml);
: y& |+ b7 o2 ]$back = socket_read($socket, 8192);

socket_read有时候收不到返回数据，应该是超时了，如何修改超时时间？
