嗨，我有一个搜索代码，但是当我运行它时它显示错误

Question

<?php  
 include('blog/includes/config.php'); //assuming $db is a database connection, quries can be done 
 using $db->query()

//Post search words
$search = $_GET['search'];

// remove any code from the search term
$search = strip_tags($search);

//No keywords entered.
if ($search == "") {
echo "<p>Opps! You forgot to enter a search term.</p>";
} else {

// perform the search
$result = $db->query("SELECT * FROM blog_posts_seo WHERE MATCH(postTitle) AGAINST(':search*' IN 
BOOLEAN MODE), ['search' => $search]");

 echo "<h3>Search Results</h3>";

echo "<p>you searched for <b>$search</b> there are ".count($results)." matches.</p>";

foreach($results as $row) { 
    echo "<h1>$row->postTitle</h1>";
    echo "<p>$row->desc</p>";
} // close while loop

  } // close else
?>

<form action="search.php" method="get">
<input name="search" type="text" size="20" />
<input type="submit" name="submit" value="Search" />
</form>

当我在输入字段中搜索时，它会显示以下消息： 致命错误：未捕获的 PDOException：SQLSTATE [42000]：语法错误或访问冲突：1064 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在 /home/takashop/domains/takashop.ir/public_html/search.php:16 的第 1 行的“['search' => پوست]' 附近使用正确的语法跟踪：#0 /home/takashop/domains/takashop.ir/public_html/search.php(16): PDO->query('SELECT * FROM b...') #1 {main} 抛出 /home/takashop /domains/takashop.ir/public_html/search.php 第 16 行

我没有遵守。可能有一些语法错误。

//Post search words
// remove any code from the search term
$search = trim(strip_tags($_GET['search']));

//No keywords entered.
if (empty($search)) {
  echo "<p>Opps! You forgot to enter a search term.</p>";
} else {

// perform the search
$stmt = $db->prepare('
Select
 * 
From
 blog_posts_seo 
Where
 Match(postTitle) AGAINST(:search* IN BOOLEAN MODE);
');
  $stmt->execute(['search' => $search]);
  echo "<h3>Search Results</h3>";

  echo "<p>you searched for <b>$search</b> there are ".$stmt->rowCount()." matches.</p>";

  while ($row = $stmt->fetch(PDO::FETCH_OBJ)) {  // you don't need the PDO::FETCH_OBJ if it's in your connect statement.
    echo "<h1>$row->postTitle</h1>";
    echo "<p>$row->desc</p>";
  } // close while loop

} // close else
