Inspired by `a recent discussion in the PHP Internals`__, I decided to provide a userland solution.
Check this:

.. __: https://externals.io/message/116127

.. code-block:: php

    <?php

    $hash = hash_init('md5');

    // vanilla functions:
    is_resource($hash); // true in PHP <= 7.1, false in PHP >= 7.2
    get_resource_type($hash); // "Hash Context" in PHP <= 7.1, various errors otherwise

    // library functions:
    \Arokettu\IsResource\is_resource($hash); // true
    \Arokettu\IsResource\get_resource_type($hash); // "Hash Context"
