在PHP中,實(shí)現(xiàn)表格(table)的動(dòng)態(tài)加載通常需要結(jié)合前端技術(shù),如JavaScript和AJAX。這里我們將使用jQuery庫(kù)來(lái)實(shí)現(xiàn)一個(gè)簡(jiǎn)單的動(dòng)態(tài)加載表格的示例。

  1. 首先,確保你已經(jīng)在HTML文件中引入了jQuery庫(kù):
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Dynamic Table</title>
   <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
    <!-- Your table and other HTML content goes here -->
</body>
</html>
  1. 創(chuàng)建一個(gè)HTML表格,用于顯示數(shù)據(jù):
   <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
            <th>Email</th>
        </tr>
    </thead>
   <tbody>
        <!-- Table data will be loaded dynamically -->
    </tbody>
</table>
  1. 編寫一個(gè)PHP腳本(例如:fetch_data.php),用于從數(shù)據(jù)庫(kù)獲取數(shù)據(jù)并返回JSON格式的結(jié)果:
<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Fetch data from the database
$sql = "SELECT id, name, email FROM users";
$result = $conn->query($sql);

$data = array();
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $data[] = $row;
    }
} else {
    echo "0 results";
}

// Return the data as JSON
header('Content-Type: application/json');
echo json_encode($data);

$conn->close();
?>
  1. 使用jQuery的$.ajax()方法從PHP腳本獲取數(shù)據(jù),并將其動(dòng)態(tài)添加到表格中:
$(document).ready(function() {
    // Load data from the PHP script
    $.ajax({
        url: 'fetch_data.php',
        type: 'GET',
        dataType: 'json',
        success: function(data) {
            // Add the data to the table
            var tableData = '';
            $.each(data, function(key, value) {
                tableData += '<tr>';
                tableData += '<td>' + value.id + '</td>';
                tableData += '<td>' + value.name + '</td>';
                tableData += '<td>' + value.email + '</td>';
                tableData += '</tr>';
            });
            $('#dynamic-table tbody').append(tableData);
        },
        error: function() {
            alert('Error loading data.');
        }
    });
});
</script>

現(xiàn)在,當(dāng)頁(yè)面加載時(shí),表格將從fetch_data.php腳本動(dòng)態(tài)加載數(shù)據(jù)。請(qǐng)注意,這個(gè)示例僅用于演示目的,實(shí)際項(xiàng)目中可能需要根據(jù)具體需求進(jìn)行調(diào)整。
