Dear experts.

I have such a feedback form on the site, I tried to supplement it with a filter of bad words. If they are found, it is supposed to display a message and list the found words.

<?php
require_once(rtrim($_SERVER['DOCUMENT_ROOT'], '/') . '/wp-load.php');

if(isset($_POST['submit'])):
    if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])):
        $secret = 'yyyyy';
        $verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response']);
        $responseData = json_decode($verifyResponse);
    
    $name = !empty($_POST['name'])?$_POST['name']:'';
    $email = !empty($_POST['email'])?$_POST['email']:'';
    $message = !empty($_POST['message'])?$_POST['message']:'';
    $useragent = $_SERVER['HTTP_USER_AGENT'];
    $comm_ip = get_ipaddress();
        if($responseData->success):
    
$badWords = array("плохое_слово1","плохое_слово2", "плохое_слово3");
$matches = array();
$matchFound = preg_match_all(
                "/\b(" . implode($badWords,"|") . ")\b/i", 
                $message, 
                $matches
              );

if ($matchFound) {
  $words = array_unique($matches[0]);
  foreach($words as $word) {
    echo "<li>" . $word . "</li>";
  }
  echo "</ul>";
}
    
      $to = '[email protected]';
      $subject = 'Сообщение';
      $htmlContent = "
        <h1>Данные отправителя:</h1>
        <p><b>Имя: </b>".$name."</p>
        <p><b>E-mail: </b>".$email."</p>
        <p><b>Сообщение: </b>".$message."</p>
      ";
      $headers = "MIME-Version: 1.0" . "\r\n";
      $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
      $headers .= 'From:'.$name.' <'.$email.'>' . "\r\n";
      wp_mail($to,$subject,$htmlContent,$headers);
      
            $succMsg = 'Ваше сообщение успешно отправлено';
      $name = '';
      $email = '';
      $message = '';
        else:
            $errMsg = 'Ошибка проверки «Я не робот», попробуйте снова.';
        endif;
    else:
        $errMsg = 'Вы забыли поставить галочку, что вы не робот. Сообщение не было отправлено.';
    endif;
else:
    $errMsg = '';
    $succMsg = '';
  $name = '';
  $email = '';
  $message = '';
endif;
?>
<html>
    <head>
    </head>
    <body>
<h2>Контактная форма</h2>

        <?php if(!empty($errMsg)): ?><div class="errMsg"><?php echo $errMsg; ?></div><?php endif; ?>
        <?php if(!empty($succMsg)): ?><div class="succMsg"><?php echo $succMsg; ?></div><?php endif; ?>

      <form action="" method="POST">
        <input type="text" class="text" required="" value="<?php echo !empty($name)?$name:''; ?>" placeholder="Введите ваше имя" name="name" >
                <input type="email" class="text" required="" value="<?php echo !empty($email)?$email:''; ?>" placeholder="Укажите ваш E-mail адрес" name="email" >
                <textarea type="text" placeholder="Сообщение..." required="" name="message"><?php echo !empty($message)?$message:''; ?></textarea>
        <div class="g-recaptcha" data-sitekey="xxx"></div>
        <input type="submit" name="submit" class="submit" value="ОТПРАВИТЬ">
    
      </form>
  </body>
</html>

I have added the code

$badWords = array("плохое_слово1","плохое_слово2");
$matches = array();
$matchFound = preg_match_all(
                "/\b(" . implode($badWords,"|") . ")\b/i", 
                $message, 
                $matches
              );

if ($matchFound) {
  $words = array_unique($matches[0]);
  foreach($words as $word) {
    echo "<li>" . $word . "</li>";
  }
  echo "</ul>";
}

But something is being ignored. How will it be right? And if possible, how to correctly display the found bad words in the same place where errMsg and succMsg are displayed

<?php
$message = "плохое_слово1 xорошее
плохое_слово2";
$badWords = array("плохое_слово1","плохое_слово2");
$matches = array();
$matchFound = preg_match_all(
                "/(" . implode($badWords,"|") . ")/mui", 
                $message, 
                $matches
              );

if ($matchFound) {
  $words = array_unique($matches[0]);
  foreach($words as $word) {
    echo "<li>" . $word . "</li>";
  }
  echo "</ul>";
}
