简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
" ^, g% [+ q$ [$ @现在socket读写数据的流程是这样的：
; P" @$ u/ z: B. e8 Y) ?
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

' D' c, F' y. P4 z- u1 Q0 E/ L0 Ysocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_write($socket, $strxml, strlen($strxml);

  t$ k5 r0 y9 ?+ }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
