    [product_data] => Array
        (
            [0] => Array
               


        

Answer 1

Short circuiting included.

function hasValues($input, $deepCheck = true) {
    foreach($input as $value) {
        if(is_array($value) && $deepCheck) {
            if($this->hasValues($value, $deepCheck))
                return true;
        }
        elseif(!empty($value) && !is_array($value))
            return true;
    }
    return false;
}
