命名空间中怎么实现全部单词替换

命名空间中如何实现全部单词替换
DataCleaner.inc.php:

PHP code

 "shortsighted",
                                "moronic" => "unreasonable",
                                "insane" => "illogical"
                             );
            
            // Remove bad words
            foreach ($badwords as $key => $value) {
                if (strpos($text, $key) !== false)
                    return str_replace($key, $value, $text);
            }
        }
    }
?>

Library.inc.php:

PHP code

index.php:

PHP code

", $title);
    
    $title = $data->RemoveProfanity($title);
    printf("Title after Data::Clean: %s
", $title);
    
    $title = $library->FilterTitle($title);
    printf("Title after Library::Clean: %s
", $title);
?>

输出：
Title before filters: the moronic sun also rises idiotic insane
Title after Data::Clean: the moronic sun also rises shortsighted insane
Title after Library::Clean: The moronic sun also rises shortsighted insane


怎么实现把所有的
"idiotic" => "shortsighted",
"moronic" => "unreasonable",
"insane" => "illogical"
这些词都替换成相应的单词？？

------解决方案--------------------
foreach ($badwords as $key => $value) {
if (strpos($text, $key) !== false)
return str_replace($key, $value, $text);
}
=================

修改为
return strtr($text, $badwords);
