简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
' i  G$ V1 ]! ^& l/ }现在socket读写数据的流程是这样的：

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
4 D' Y6 a) N, y1 \0 Q# D
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

- }1 Q" i4 l8 Z" Bsocket_connect($socket, IP, PORT);
$ |0 N) I$ Z! X; {% \2 ?
socket_write($socket, $strxml, strlen($strxml);
# t6 h* }' N4 o+ G5 X$back = socket_read($socket, 8192);
7 m% s+ y, m$ N0 O/ I* W: m
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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
+ }# H& Q& F2 z8 v5 }socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
