Question

我有使用实时AJAX搜索引擎编写的代码，该代码从MySQL数据库中搜索“术语”，其中包含3列ID，标题，描述。

由于某些原因，芬兰语言和波斯/阿拉伯语言字母的特殊字符不可读。在MySQL数据库中，一切都应该很好，因为放置了排序规则为utf8_general_ci的列以及放置在utf8的索引文件中。

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

字符äöå像��和阿拉伯字符一样显示为????????。 php代码是：

if(isset($_GET['p'])) {
  $page_number = $_GET['p'];
  $arraySearch = $_GET['terms'];
  $show_count = $_GET['count'];
  settype($page_number, 'integer');
}
    $nospaces = substr ($_GET['terms'],0,4);
    $offset = ($page_number - 1) * $records_number;
// check for an empty string and display a message.
if ($_GET['terms'] == "") {
  echo  '<div id="counter">Kirjoita, että olet homo!</div>';
// minim 3 characters condition
  } else if(strlen($_GET['terms']) < $limitchar) {
 echo '<div id="counter">'. $limitchar .' characters minimum</div>';

  } else  {

// explode search words into an array
  $arraySearch = explode(" ", $_GET['terms']);
// table fields to search
  $arrayFields = array(0 => $first_field, 1 => $second_field);
  $countSearch = count($arraySearch);
  $a = 0;
  $b = 0;
  $query = "SELECT * FROM $table_name WHERE (";
  $countFields = count($arrayFields);
  while ($a < $countFields)
  {
    while ($b < $countSearch)
    {
      $query = $query."$arrayFields[$a] LIKE '$arraySearch[$b]%'";
      $b++;
      if ($b < $countSearch)
      {
        $query = $query." AND ";
      }
    }
    $b = 0;
    $a++;
    if ($a < $countFields)
    {
      $query = $query.") OR (";
    }
  }
  $query = $query.") LIMIT $offset, $records_number;";
  $search = mysqli_query($connect, $query);


// get number of search results
  $arrayFields = array(0 => $first_field);
  $countSearch = count($arraySearch);
  $a = 0;
  $b = 0;
  $query = "SELECT * FROM $table_name WHERE (";
  $countFields = count($arrayFields);
  while ($a < $countFields)
  {
    while ($b < $countSearch)
    {
      $query = $query."$arrayFields[$a] LIKE '%$arraySearch[$b]%'";
      $b++;
      if ($b < $countSearch)
      {
        $query = $query." AND ";
      }
    }
    $b = 0;
    $a++;
    if ($a < $countFields)
    {
      $query = $query.") OR (";
    }
  }
  $query = $query.")";
  $count_results = mysqli_query($connect, $query) or die(mysqli_error($connect));

  $numrows = mysqli_num_rows($count_results);

// no results
if($numrows == 0) {
        echo '<div id="counter">No results found</div>';

// show results
} else {

echo '<div id="results">
<div id="results_top"><p><b>'. $_GET['terms'] .'</b> - '. $numrows .' results found</p></div>
';

while($row = mysqli_fetch_assoc($search)) {

$title = ($row['title']);

echo '

<div class="item">
    <div class="word"><a'.$title.'-'.$row['id'].' class="title">'.$row['title'].'</a></div>
    <div class="description" dir="rtl">'.$row['description'].'</div>

<div style="clear:both;"></div></div>'; 
}

MySQL版本：5.6.36 PHP版本：7.0.23

有什么建议吗？该代码也已生效，地址为：http://dic.munjutut.fi/php/ 如果键入äiti或aälto，则显示结果。

特殊字符如äöå和阿拉伯/波斯字母
