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

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
( d$ H& B: A+ ^4 j  D9 _/ s* [
3 \3 k4 a" @) vsocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

' Q# u8 s% @6 p0 ~; F% T; H+ d& A
0 C5 f" T+ W% Xsocket_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？
