Question

我有一个匹配错误单词的功能。我希望得到匹配的词。

Public function store(PostRequest $request){ 
    $post = Post::create($request->validated());
    $warningWords = Word::where('type', 'warning_words')->pluck('content')->toArray();
    if($this->match($forbiddenPhrases, $thought_content)){
        Flagable::create('status' => '2', 'word' => '', 'word_id' => '']);
    }
}

private function match($needles, $haystack){
    foreach($needles as $needle){
        if (strpos($haystack, $needle) !== false) {
            return true;
        }
    }
    return false;
}

如何将匹配的单词存储在创建语句列“单词”中

Answer 1

我认为最好的解决方案是让函数在发现任何单词时返回单词，而在没有发现任何单词时返回null。

private function match($needles, $haystack)
{
    foreach ($needles as $needle) {
        if (strpos($haystack, $needle) !== false) {
            return $needle;
        }
    }
}

现在，您可以使用if语句检查是否返回了单词：

$word = $this->match($forbiddenPhrases, $thought_content)
if ($word) {
    Flagable::create(['status' => '2', 'word' => $word, 'word_id' => '']);
}

像这样更改您的功能：

private function match($needles, $haystack){
     foreach($needles as $needle){
         if (strpos($haystack, $needle) !== false) {
             return needle;
          }
     }
     return false;
 }

，然后像这样更改您的代码：

 Public function store(PostRequest $request){ 
        $post = Post::create($request->validated());
        $warningWords = Word::where('type', 'warning_words')->pluck('content')->toArray();
        if(($word = $this->match($forbiddenPhrases, $thought_content)) !== false){
            Flagable::create('status' => '2', 'word' => $word, 'word_id' => '']);
        }

}

Answer 3

   /**
     * Checks and returns all forbiddenPhrases found in the content
     * 
     * @param  array  $forbiddenPhrases
     * @param  string $content
     * 
     * @return array
     */
    private function match(array $forbiddenPhrases, string $content){

        $content = strtolower($content);
        $forbiddenPhrases = array_map('strtolower', $forbiddenPhrases);

        return  array_filter($forbiddenPhrases, function($word){

            return str_contains($content, $word);
        });
    }

然后在控制器中可以执行以下操作：

$forbiddenPhrases = Word::where('type', 'warning_words')->pluck('content', 'id')->toArray();
$foundForbiddenPhrases = $this->match($forbiddenPhrases, $content);

if(count($foundForbiddenPhrases) > 0){

    foreach ($foundForbiddenPhrases as $phraseId => $foundForbiddenPhrase) {
        Flagable::create('status' => '2', 'word' => $foundForbiddenPhrase, 'word_id' => $phraseId]);
    }
}

将集合中匹配的单词存储在db中
