Equals sign not aligned with surrounding assignments; expected 2 spaces but found 1 space

        $strClass = '';

$strClass is not used, you could remove the assignment.

        for ($i = 0; $i < count($classes); ++$i) {

It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.

            $class = $classes[$i];

            if (preg_match('/\s|,|;/', $class)) {
                $class = sprintf("'%s'", $class);
            }
            $classes[$i] = $class;
        }

        return implode(',', $classes);
    }
}
