为什么我在使用file_get_contents（）时遇到500错误，但在浏览器中有效？

Question

$html = file_get_contents("https://www.[URL].com"); 
echo $html;

produces this in the error logs:

PHP Warning: file_get_contents(https://www.[URL].com) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error in /Applications/MAMP/htdocs/test.php on line 13";

However, the site works fine in a browser.

I tried using cURL as well. I don't get any errors in the log file, but $html now echoes:

Server Error in '/' Application.
Object reference not set to an instance of an object.

...some more debugging info

Any ideas how to work around this?

Answer 1

Try this workaround:

$opts = array('http'=>array('header' => "User-Agent:MyAgent/1.0
"));
$context = stream_context_create($opts);
$header = file_get_contents('https://www.example.com',false,$context);

If this doesn't work, maybe you cant read from https?
