note 2314 deleted from fopen by ronabop

I had an code to open remote URL by <br> fopen("$url","r"); It worked before. But it does not work now! It gives error msg:<br> Warning: fopen("http://www.metu.edu.tr/","r") - Transport endpoint is not connected in /home/sait/public_html/TEST/test.php3 on line 42<br> When I changed hostname with IP, it works. When I tried to change hostname to the IP by using gethostbyname, it does not works!!! it gives itself as result. The problem is in version PHP 3.0 OR I need to talk with system admin, for posiable DNS problems??
