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：

  ]( x9 H, k  \) U; c  C$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
; b* H0 G8 X' V/ N7 @1 g
' U9 y7 n5 l# M% R, ?socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
3 E' C1 a' b' u0 ^2 I
socket_connect($socket, IP, PORT);
" N, i; }) g# q( m8 S4 X) @
socket_write($socket, $strxml, strlen($strxml);
$ b' T7 [7 S# D$back = socket_read($socket, 8192);
" u3 e1 l  y- g) T8 G/ K
9 r7 K; Q" l! {' i' osocket_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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
8 H: `. p* T# wsocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
