Why Does My PHP `file_get_contents()` Return a 500 Error While the Website Loads in My Browser?

Troubleshooting 500 Error with file_get_contents() Despite Browser Access

When attempting to retrieve web content using PHP's file_get_contents() function, you may encounter a 500 Internal Server Error. However, accessing the same site in a web browser may yield no issues. This inconsistency highlights a potential problem.

To troubleshoot this issue, you employed cURL as an alternative approach. However, utilizing cURL seemed to produce a different error message: "Object reference not set to an instance of an object."

A possible solution to this problem is utilizing the following workaround:

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

This workaround aims to simulate a browser agent's request by setting a custom User-Agent header. This may resolve the issue if the web server distinguishes between browser and script requests.

If this workaround fails, it's possible that your server configuration does not grant you access to HTTPS resources. You may need to adjust your server settings accordingly to enable HTTPS requests.
