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：

5 f- I9 P* m0 q* o! y$ H, F$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
# S2 L# B& e' w# e: n" }  G: C/ R' V
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
; v8 e  w4 ]4 v8 S3 Y- K( H
socket_connect($socket, IP, PORT);
( r- p2 k$ F& o' l) }, q  `
% x+ s4 k& k. t) b) r( x% u7 p& osocket_write($socket, $strxml, strlen($strxml);
% a( N/ b9 v5 _- N" e7 V. E) B$back = socket_read($socket, 8192);

0 e+ o  Y8 s) W- k( x- Bsocket_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？
1 S1 M7 d1 W# W% q6 C" Qsocket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
