Question

我正在尝试这样做，以便在标题链接中显示最新公告。我已经尝试过这样做了，现在我只是试图让它甚至返回变量而且它不会...

的functions.php

<?php
    require("common.php");
    function getAnnouncements() {
        $query = "SELECT * FROM announcements";

        try {
            global $db;
            // Execute the query against the database
            $stmt = $db->prepare($query); 
            $result = $stmt->execute();
            echo $result['title'];
        }
        catch(PDOException $ex) { 
            // Note: On a production website, you should not output $ex->getMessage(). 
            // It may provide an attacker with helpful information about your code.  
            die("Failed to run query: " . $ex->getMessage()); 
        } 

    }

?>

的index.php

    <div class="announcement">
        <div class="container">
            Latest Announcements: <?php getAnnouncements(); echo "<a href=''></a>" ?>
        </div>
    </div>

是的，我将文件包含在顶部，并且没有拼写错误。

首先，确保$db初始化为：

 $db = new PDO("mysql:host=[host here];dbname=[dbname]e;charset=utf8",[username],[password]);

你想要获取一个关联数组并像这样循环：

$result = $result->fetchAll(PDO::FETCH_ASSOC);
for($result as $a_result)
    echo '<a href="'.$a_result['link'].'">'.$a_result['title'].'</a>';

这假设数据库中有link列
