get_headers() returns "HTTP request failed!"

[Jabop]

Code:

<?php
// www.digg.com
print_r(get_headers('http://www.digg.com', 1));

// digg.com
print_r(get_headers('http://digg.com', 1));
?>

 

 

Response:

Warning: get_headers(http://www.digg.com) [function.get-headers]: failed to open stream: HTTP request failed! in /home/jacob/workspace/tester.php on line 3

 

Warning: get_headers(http://www.digg.com) [function.get-headers]: failed to open stream: HTTP request failed! in /home/jacob/workspace/tester.php on line 6

 

Any idea why this isn't working?

Is allow_url_fopen set to true within your php.ini? If not the function will fail right away.

Oni-kun, if allow_url_fopen was not set to true, it would have thrown another error message explicitly stating such.

 

I found out why it wasn't working. Some sites are finicky when it comes to user agents, so I set this at the beginning of my script:

 

<?php
ini_set('user_agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.16) Gecko/2009121601 Ubuntu/9.04 (jaunty) Firefox/3.0.16');
