在命令行的时候能正确输出...可是在ie里面调用的时候只会返回个空白页面...在err_log 里面 显示是
Fri Nov 11 19:07:49 2005] [error] PHP Warning:  file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /var/www/htdocs/1.php on line 14

是连接超时了... 请问该如何解决呢?

http://w.yi.org/ftp/FAPM/PHP/php ... ini.allow-url-fopen

这个允许了么？

allow_url_fopen = On

; Define the anonymous ftp password (your email address)
;from="john@doe.com"

; Define the user agent for php to send
;user_agent="PHP"

; Default timeout for socket based streams (seconds)
default_socket_timeout = 60

应该是激活了..用的是slackware的默认设置

域名解析不对吧? 试试 telnet www.chinaunix.net 80
或者 ping 什么看看, 检查一下 /etc/resolv.conf 的设置

再者, 如果说 services 不存在,难道 /etc/services 里面没有关于 HTTP 端口的定义?(不太可能)
