简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
现在socket读写数据的流程是这样的：
: E5 C: z$ v5 j% ?0 Y
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

  M0 t& i, o" w# ?- ~, ?socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
: K6 u6 ]* n; R& z4 S# R2 R2 U
) s/ `! A9 d% F0 b; Xsocket_connect($socket, IP, PORT);

5 J( n' T9 G/ x8 H4 [6 dsocket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);
2 X' y) P& u0 _  R  ^
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？
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
! f# }- J& M7 U" k: }7 p- Dsocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
