您需要将 max_redirects 上下文选项设置为 1 或仅禁用 follow_location:

$context = stream_context_create(
    [
        'http' => [
            'follow_location' => 0,
        ],
    ]
);
$headers = get_headers("http://example.com/test", true, $context);
var_dump($headers);

Reference :

follow_location int

Follow Location header redirects. Set to 0 to disable.

Defaults to 1.

max_redirects int

The max number of redirects to follow. Value 1 or less means that no redirects are followed.

Defaults to 20.
