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：

" O/ G/ {6 n' [$ r$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
1 J$ g  K5 {4 g9 P
. R. i7 d+ S/ H7 J3 S  V9 S+ Z; msocket_connect($socket, IP, PORT);

' i6 j( n, o2 N6 csocket_write($socket, $strxml, strlen($strxml);
$back = socket_read($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？
  v( C5 T# P+ x  S) p! Z! h6 q6 ~socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
