为什么我的 MySQL 数据没有显示在我的表中？一切似乎都很好，只是我的数据（这是鸟类名称列表等）没有显示出来。我需要一些新的眼光，才能看到我的错误在哪里，是的，我知道可能有更简单的方法可以做到这一点，但这是我的任务所必需的，所以请不要提供其他方法来做到这一点。我需要的只是帮助让我的数据填充到 HTML 表中。我的PHP代码如下：
PHP 代码
<?php
$pageTitle = 'Mod06 Pagination| Jason McCoy ';

$display = 8;
// Determine how many pages there are...
if (isset($_GET['p']) && is_numeric($_GET['p'])) { // Already been determined.
$pages = $_GET['pages'];
} else {
$query = "SELECT COUNT(birdID) FROM birds";
$result = @mysqli_query($dbc, $query);
$row = @mysqli_fetch_array($result, MYSQLI_NUM);
$records = $row[0];
}
// Calculate the number of pages...
if ($records > $display) {
$pages = ceil($records/$display);
} else {
$pages = 1;
}
// Determine where in the database to start returning results...
if (isset($_GET['s']) && is_numeric($_GET['s'])) {
$start = $_GET['s'];
} else {
$start = 0;
}
// Sort the columns
// Default is birdID
$sortDefault = 'birdID';
// Create an array for the columns
$sortColumns = array('birdID', 'nameGeneral', 'nameSpecific', 'populationTrend');
// Define sortable query ASC DESC
$sort = (isset($_GET['sort'])) && in_array($_GET['sort'], $sortColumns) ? $_GET['sort']: $sortDefault;
$order = (isset($_GET['order']) && strcasecmp($_GET['order'], 'DESC') == 0) ? 'DESC' : 'ASC';
// Run the query
$query = "SELECT birdID, nameGeneral, nameSpecific, populationTrend FROM birds ORDER BY $order LIMIT $start, $display";
$result = @mysqli_query($dbc, $query);
