http - php : curl fsockopen 去访问站点时候，相应时间特别长
php : curl fsockopen 去访问放在我的一个服务器上的站点时候，响应时间特别长，时间>10s，推测，和服务器的配置有关,用浏览器访问正常。请问，大家这个是什么引起？

直接访问ip如何呢，看看是不是DNS解析的问题
此时定位问题最重要了
1:可线检查下curl的超时时间设置（CURLOPT_TIMEOUT），这个值最小是1s（当然可以通过修改指定到毫秒级），比如设置5s看下，如果获取不到内容可以ping url，看是不是本地dns解析有问题
2:打开服务器的日志(nginx的访问日志和php的日志）到这里应该一目了然
