How to write a simple online reservation system through PHP
With the popularity of the Internet and users' pursuit of convenience, online reservation systems are becoming more and more popular. Whether it is a restaurant, hospital, beauty salon or other service industry, a simple online reservation system can improve efficiency and provide users with a better service experience. This article will introduce how to use PHP to write a simple online reservation system and provide specific code examples.
- Create database and tables
First, we need to create a database to store reservation information. Create a database named "appointment" in MySQL and create a data table named "appointments" containing the following fields:
id INT(11) PRIMARY KEY AUTO_INCREMENT name VARCHAR(50) email VARCHAR(50) phone VARCHAR(20) date DATE time TIME
- Create appointment form
Next, we need to create a reservation form for users to fill out. In the HTML file, add the following code:
<form method="post" action="process.php"> <input type="text" name="name" placeholder="姓名" required> <input type="email" name="email" placeholder="郵箱" required> <input type="tel" name="phone" placeholder="電話" required> <input type="date" name="date" required> <input type="time" name="time" required> <button type="submit">提交預(yù)約</button> </form>
- Processing appointment requests
Create a PHP file named "process.php" to handle appointment requests. In this file we need to receive the form data and insert it into the database. Add the following code:
<?php
// 連接數(shù)據(jù)庫
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "appointment";
$conn = new mysqli($servername, $username, $password, $dbname);
// 檢查連接是否成功
if ($conn->connect_error) {
die("連接失敗: " . $conn->connect_error);
}
// 處理預(yù)約請求
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$date = $_POST['date'];
$time = $_POST['time'];
$sql = "INSERT INTO appointments (name, email, phone, date, time)
VALUES ('$name', '$email', '$phone', '$date', '$time')";
if ($conn->query($sql) === TRUE) {
echo "預(yù)約成功！";
} else {
echo "預(yù)約失?。?quot; . $conn->error;
}
$conn->close();
?>- Display appointment list
In order to facilitate the management of appointment information, we can create a page to display the appointment list. In a new PHP file, add the following code:
<?php
// 連接數(shù)據(jù)庫
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "appointment";
$conn = new mysqli($servername, $username, $password, $dbname);
// 檢查連接是否成功
if ($conn->connect_error) {
die("連接失敗: " . $conn->connect_error);
}
// 獲取預(yù)約列表
$sql = "SELECT * FROM appointments";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) {
echo "姓名: " . $row['name'] . "<br>";
echo "郵箱: " . $row['email'] . "<br>";
echo "電話: " . $row['phone'] . "<br>";
echo "日期: " . $row['date'] . "<br>";
echo "時(shí)間: " . $row['time'] . "<br>";
echo "<br>";
}
} else {
echo "暫無預(yù)約信息";
}
$conn->close();
?>By accessing the above page, you will be able to see a list of appointments, including the name, email, phone number, date and time of each appointment.
The above is the implementation method of a simple online reservation system. Writing an online reservation system using PHP is not only simple and easy to understand, but also very flexible. You can modify and expand it according to actual needs. Hope this article helps you!

How to use PHP to build social sharing functions PHP sharing interface integration practice
Jul 25, 2025 pm 08:51 PM
The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.
PHP calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.
How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization
Jul 25, 2025 pm 08:57 PM
To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X
PHP creates a blog comment system to monetize PHP comment review and anti-brush strategy
Jul 25, 2025 pm 08:27 PM
1. Maximizing the commercial value of the comment system requires combining native advertising precise delivery, user paid value-added services (such as uploading pictures, top-up comments), influence incentive mechanism based on comment quality, and compliance anonymous data insight monetization; 2. The audit strategy should adopt a combination of pre-audit dynamic keyword filtering and user reporting mechanisms, supplemented by comment quality rating to achieve content hierarchical exposure; 3. Anti-brushing requires the construction of multi-layer defense: reCAPTCHAv3 sensorless verification, Honeypot honeypot field recognition robot, IP and timestamp frequency limit prevents watering, and content pattern recognition marks suspicious comments, and continuously iterate to deal with attacks.
PHP realizes commodity inventory management and monetization PHP inventory synchronization and alarm mechanism
Jul 25, 2025 pm 08:30 PM
PHP ensures inventory deduction atomicity through database transactions and FORUPDATE row locks to prevent high concurrent overselling; 2. Multi-platform inventory consistency depends on centralized management and event-driven synchronization, combining API/Webhook notifications and message queues to ensure reliable data transmission; 3. The alarm mechanism should set low inventory, zero/negative inventory, unsalable sales, replenishment cycles and abnormal fluctuations strategies in different scenarios, and select DingTalk, SMS or Email Responsible Persons according to the urgency, and the alarm information must be complete and clear to achieve business adaptation and rapid response.
How to use PHP to combine AI to generate image. PHP automatically generates art works
Jul 25, 2025 pm 07:21 PM
PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.
