fopen（）需要十秒钟或更长时间才能回来...... [英] fopen() taking ten seconds or more to come back...

问题描述

几个月来我一直在使用...


$ fp = fopen（" http://www.weather.gov/data/current_obs/KPKB.xml" ;，r）;


....打开xml文件，然后我解析它以提取当地的

天气数据，以及它起作用了。


最近，该页面已经开始挂起，并且通过阻止

部分代码并计时我追踪的不同部分延迟

到fopen（）语句。


脚本几乎是瞬间从我的本地驱动器运行，

访问远程网址，但需要10秒或11秒，

来自网络。


我怀疑我的网络提供商发生了变化，但他们是

仍在运行PHP 4.3.1并且allow_url_fopen已开启& on。


有什么想法吗？

也许weather.gov阻止/制止他们的IP号码。

For months I''ve been using...

$fp = fopen("http://www.weather.gov/data/current_obs/KPKB.xml","r");

.... to open the xml file, which I then parse to extract the local
weather data, and it has worked swell.

Just lately, the page has started hanging, and by blocking off
sections of code and timing different sections I''ve traced the delay
to that fopen() statement.

The script runs nearly instantaneously from my local drive,
accessing the remote URL, but takes ten or eleven seconds,
consistently, from the web.

I suspected something changed with my web provider, but they''re
still running PHP 4.3.1 and allow_url_fopen is on & on.

Any ideas?

Maybe weather.gov is blocking/putting a brake on their ip no.
