Maybe this?

ini_set('user_agent', 'Mozilla/5.0');

For anyone else coming here, the best option (instead of a server-wide change, which who knows what might break), is to use stream context options (the user agent option, in particular).

The PHP documentation already shows an example for change the HTTP method (sadly, also using a global setting 🤦).

In any case, the code would be something like:

$context = stream_context_create([ 'http' => [ 'user_agent' => 'Mozilla/5.0' ] ]); $headers = get_headers('http://example.com', true, $context);

get_headers only specifies the data sent by the server to the client (in this case, PHP), it doesn't specify request headers.

If you're trying to find the user agent the get_headers request was made with, you'll have to use:

ini_get('user_agent');
