New helper to check if some string is json

[Zen0x7]

Yeah. I'm pretty sure that should be a feature of PHP but no function is created.

I have been looking for different implementations and the following is really nice:

function is_json(string $var) {
    return json_decode($var) && json_last_error() === JSON_ERROR_NONE;
}

What you think?

json_validate will be available in PHP 8.3: https://wiki.php.net/rfc/json_validate and you can already use polyfill from https://github.com/symfony/polyfill-php83 right now
