简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
9 J& @2 P: `4 t  F* g( B- j9 G) `现在socket读写数据的流程是这样的：
( E3 L; q; c- p0 c4 i& ?
! a: x2 w( k# r/ g4 z$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
! ?1 A5 k2 Y7 h0 \* t" w4 c' w7 d
4 z# F, T9 H9 y7 B) x7 usocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

& a" V% v! R4 K8 Ysocket_connect($socket, IP, PORT);
8 ^! w, `) S. Q
/ Q. @, ^! d, }' c, esocket_write($socket, $strxml, strlen($strxml);
3 r( h% y) J( Q5 w$back = socket_read($socket, 8192);
* ]. \- h2 L$ D. _8 a
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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
