PHP Get a faraway file

PHP Get remote Files
if (! ( $contents =file_get_contents (' HTTP://FINANCE.YAHOO.COM/D/QUOTES.CSV?S=AMZN&E=.CSV&F=SLLDLTLCLOHGV ')) {
Die (' fail to open Yahoo ');
};
Echo $contents;


Why the average refresh of 3-4 is only one success, the other will appear a warning, prompting HTTP request failed!

In the XX on line yyif you is behind a SonicWall firewall, read this:https://bugs.php.net/bug.php?id=40197 (This little line:  Uncheck a box in the internal settings of the firewall labled ' enforce Host Tag Search with for CFS ' apparently by default SonicWall blocks any HTTP request without a "Host:" header, which are the caseIn the PHP get_file_contents (URL) implementation. This is what, if you try to get the same URL from the same machine with CURL our wget, it works. I hope this'll be useful to someone, it took me hours to find out:) godwraith01 at yahoo dot com 11-oct-2011 04:16i expe Rienced a problem in using the hostnames instead straight IP with some server destinations. If I use file_get_contents ("Www.jbossServer.example/app1",...) I'll get a ' Invalid hostname ' from the server I ' m calling. This is because file_get_contents probably would rewrite your request after getting the IP, obtaining the same thing As:fi Le_get_contents ("Xxx.yyy.www.zzz/app1",...) And you know that many servers would deny you access if you go through IP addressing in the request. With CURL This problem doesn ' t exists.  it resolves the hostname leaving the request as you set it up, so the server was not rude in response.
