Summary

Simple formatter broken with non-array value extra array key when using PHP version 8++.

How to reproduce

        $date   = new DateTime('2012-08-28T18:15:00Z');
        $fields = [
            'timestamp'    => $date,
            'message'      => 'foo',
            'priority'     => 42,
            'priorityName' => 'bar',
            'extra'        => null,
        ];
        $formatter = new Simple();
        echo $formatter->format($fields);
        // Throws error: TypeError: count(): Argument #1 ($value) must be of type Countable|array, string given

        $date   = new DateTime('2012-08-28T18:15:00Z');
        $fields = [
            'timestamp'    => $date,
            'message'      => 'foo',
            'priority'     => 42,
            'priorityName' => 'bar',
            'extra'        => '',
        ];
        $formatter = new Simple();

        echo $formatter->format($fields);
        // Throws error: TypeError: count(): Argument #1 ($value) must be of type Countable|array, string given

Expected behavior

        $date   = new DateTime('2012-08-28T18:15:00Z');
        $fields = [
            'timestamp'    => $date,
            'message'      => 'foo',
            'priority'     => 42,
            'priorityName' => 'bar',
            'extra'        => null,
        ];
        $formatter = new Simple();
        echo $formatter->format($fields);
        // Output: 2012-08-28T18:15:00+00:00 bar (42): foo

        $date   = new DateTime('2012-08-28T18:15:00Z');
        $fields = [
            'timestamp'    => $date,
            'message'      => 'foo',
            'priority'     => 42,
            'priorityName' => 'bar',
            'extra'        => '',
        ];

        $formatter = new Simple();
        echo $formatter->format($fields);
        // Output: 2012-08-28T18:15:00+00:00 bar (42): foo
