mysql_select_db("") or die( "Could not connect to database");

$names[] = mysql_query("SELECT * FROM list ORDER BY name ASC");

// The list wasn't sorted, if you don't want sorting you can just remove this line.
asort($names);

// Prepare list for accordion.
$accordionData = [];
foreach($names as $name) {
  $accordionData[substr($name, 0, 1)][] = $name;

我收到两个错误：

警告：substr() 期望参数 1 是字符串，资源在第 14 行的 C:\xampp\htdocs\test.php 中给出

警告：ucfirst() 期望参数 1 是字符串，资源在 C:\xampp\htdocs\test.php 第 49 行给出

如果我将名称从数组中取出，我将如何将名称放入手风琴？

使用mysql_fetch_*函数来处理 mysql_query 返回的资源。

$qry = mysql_query("SELECT * FROM list ORDER BY name ASC");

while ($data = mysql_fetch_assoc($qry))
  echo $data['name']; // contains list.name from your db

此外，您更喜欢使用PDOmysql_* 自 5.3 以来已弃用。看看那里。

mysql_query()函数运行一条 SQL 语句并（如果这是一条SELECT语句）返回一个结果。您必须使用合适的函数（如mysql_fetch_array()or ）处理此结果mysql_fetch_assoc()。

$result = mysql_query("SELECT * FROM list ORDER BY name ASC");

$names = mysql_fetch_assoc($result);

然后在循环 ( )中使用$names带有字段键的数组。while例如，$names["name"]获取当前行的名称字段值。

<div id="accordion">
    <?php
        // Print accordion, change the echoes to reflect your accordion html.
        while($names = mysql_fetch_assoc($result))
        {
            echo "<h3>" . substr(strtoupper($names["name"]),0,1) . "</h3>";
            //first letter of the name
            echo "<div>";

            foreach($names as $name) 
            {
                echo  "<p>" . ucfirst($name) . "</p>";
            }
            echo "</div>";
        }
    ?>
</div>

是的，我们知道mysql_*已弃用。
