The detailed mode for Phalcon/Debug is not work

[limingxinleo]

When I use Phalcon/Debug detailed mode,The result is not expected.

<?php
        $obj = new \stdClass();
        $obj->aaa = 111;

        array_map(function ($x) {
            $string = (new \Phalcon\Debug\Dump(null, true))->variable($x);

            echo(PHP_SAPI == 'cli' ? strip_tags($string) . PHP_EOL : $string);

        }, [$obj]);

The Result

The argument is not initialized or iterable() code:0 in phalcon/debug/dump.zep line 215
#0 [internal function]: Phalcon\Debug\Dump->output(Object(stdClass), '')
#1 /Users/limx/Applications/limingxinleo/basic-phalcon/app/Tasks/TestTask.php(16): Phalcon\Debug\Dump->variable(Object(stdClass))

#9 {main}%

I find the source code for Phalcon/Debug/Dump, using for instead of each, for is not support object, so it throw a exception, but each is deprecated for php7.2.
