How Can I Retrieve HTTP Response Codes Using `file_get_contents` and `stream_context_create`?

Retrieving HTTP Response Code with file_get_contents and stream_context_create

When utilizing file_get_contents and stream_context_create for POST requests, handling HTTP errors is crucial. By default, file_get_contents raises warnings when encountering HTTP errors, making it difficult to retrieve the response code.

To suppress these warnings and obtain the response code, you can leverage the following solution:

Suppressing Warnings and Retrieving Response Code

1. Create a stream context using stream_context_create with the following options:

$options = [
    'http' => [
        'ignore_errors' => true
    ]
];

The 'ignore_errors' option suppresses warnings generated by file_get_contents.

2. Utilize file_get_contents with the created stream context to retrieve the response:

$result = file_get_contents("http://example.com", false, $context);

3. After retrieving the response with file_get_contents, the HTTP response header information, including the response code, will be available in the global $http_response_header variable. You can access the response code as follows:

var_dump($http_response_header);

This technique allows you to handle HTTP errors gracefully without warnings and retrieve the response code from the stream.
