I have this helper function I use to log (into the serverside output) some events in my laravel app and is just working fine, but for a reason I can’t understand it fails with this specific case:

public static function consolelog(...$args): void{
    foreach ($args as $arg) {
        if (is_object($arg) || is_array($arg) || is_resource($arg)) {
            $output = print_r($arg, true);
        } else {
            $output = (string) $arg;
        }

        fwrite(STDOUT, $output . "n");
     }
}

In a middleware I verify a case where I want to abort a request but instead the app is just crashing when I try to print the string " URI:" and it makes no sense to me why is it happening just for this case:

Funcoes::consolelog("Requisição inválida, headers:n");
Funcoes::consolelog(getallheaders());
Funcoes::consolelog(" Remote addr:");
Funcoes::consolelog($_SERVER['REMOTE_ADDR']);
Funcoes::consolelog(" URI:"); // it fails here without even printing the string
Funcoes::consolelog($_SERVER['REQUEST_URI']);
abort(400);

Error message:

In ServeCommand.php line 381:

Undefined array key 1

Php -v output (in case it’s useful):
