简单实用socket

czk

@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
现在socket读写数据的流程是这样的：

1 U3 |$ g$ L; M; q" h$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
! J: R% C4 a+ [4 h8 z6 a% u' [
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
& p5 R% P  j( f( |0 b: f
socket_connect($socket, IP, PORT);
/ f2 x, g* b) B; l0 F
  U3 P  {6 p7 C3 {/ ^7 c+ @) i, Z8 ksocket_write($socket, $strxml, strlen($strxml);
& t0 t' z# K7 x& v$back = socket_read($socket, 8192);
8 ?- X! M! b( {0 E
, s! {3 k9 g* k8 psocket_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？
