php不管curl还是file_get_contents请求接口都很慢，但直接在浏览器里访问就很快，这是说明情况？

http

api

curl

get

这是接口：
http://api.k780.com:88/?app=w...

现在问题就是无论我怎么用curl或者是file_get_contents()来请求接口都很慢，自己也查了下，说是将域名换成ip就好了,但ip有时候会跟换，而且这网站配置了虚拟域名，用ip访问不了

想问下有没有方法能缩短时间？

遇到了一样的问题，你这个url直接访问只有0.12s，但通过php访问5.3s

使用xdebug或者xhprof进行性能分析。

不慢吖，试了请求返回0.2s

你确定是php在这一步慢？最好将整个PHP执行顺序依次输出时间戳看一下到底哪一步慢。

简单用curl测了下，三次分别耗时0.229s, 0.127s和0.117s，挺快的呀。从浏览器访问也是这个速度。 LZ还是应该检查代码，是不是在其他地方有高耗时的操作 -- 代码看不出来的话就打点看看时间呗。
