[代码]

<?php
mysql_connect("","","") or die("Could not connect to localhost");
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;
}

?>

    <p><?php echo ucfirst($name); ?></p>

我收到两个错误：

警告：substr（）期望参数1为字符串，资源为   第14行的C：\ xampp \ htdocs \ test.php

警告：ucfirst（）期望参数1为字符串，资源为   第49行的C：\ xampp \ htdocs \ test.php

如果我把名字从数组中删除，我怎么能把名字输入手风琴？

Answer 1

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PDO，因为自5.3以来不推荐使用mysql_ *。看看它there。

Answer 2

mysql_query()函数运行SQL语句，并且（如果这是SELECT语句）返回结果。您必须使用mysql_fetch_array()或mysql_fetch_assoc()等合适的函数处理此结果。

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

$names = mysql_fetch_assoc($result);

然后在循环中使用带有字段键的$names数组（while）。例如，$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_*已被弃用。
