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：

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

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

socket_connect($socket, IP, PORT);
+ d# e: w4 `3 [8 w" }$ X" m
8 \4 [( X9 y1 Rsocket_write($socket, $strxml, strlen($strxml);
' @6 r) s6 f7 Q6 e$back = socket_read($socket, 8192);
8 L4 Q9 h/ w) E, d1 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？
