Comment

The deprecation notice you received in PHP is related to the http_build_query function in the url.php library. Specifically, the notice is warning you that passing null to the $numeric_prefix parameter (which is expected to be a string) is deprecated, meaning that this usage will likely be removed in future versions of PHP.

To fix the issue, you can pass an empty string ('') instead of null to the $numeric_prefix parameter, like this:
$query = http_build_query($params, '', '&', PHP_QUERY_RFC3986);

Alternatively, if you do not need to specify a numeric prefix for your query parameters, you can simply omit the $numeric_prefix parameter altogether, like this:

$query = http_build_query($params, '', '&');

This will use the default value for the $numeric_prefix parameter, which is an empty string (''), and will also prevent the deprecation notice from being triggered.

It's generally a good practice to address deprecation notices as soon as possible to ensure that your code is compatible with future versions of PHP.
