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
: E8 A7 y' ]: ?1 h, `现在socket读写数据的流程是这样的：

6 [( s, p1 q/ _& {/ H  G8 j$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);

; P) P( c; l) s' I! u8 jsocket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);
; z3 R- N, d* P5 Q. u* u6 L
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？
8 ?2 l6 ~% h% l1 h& _/ x6 Isocket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
8 C$ L3 H8 [5 Q) q1 Fsocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
