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

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
3 c) j* g; _* ?2 r. M1 h
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);

socket_write($socket, $strxml, strlen($strxml);
. ?7 T8 O+ @; C; u( l$back = socket_read($socket, 8192);
( k; H2 C( b1 m4 z) D( b6 P2 I
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？
