Summary<br>This article introduces how to use PHP to implement a simple online order management system, including the creation, modification, query and deletion of orders. Through the sample code in this article, readers can learn how to use PHP and MySQL to implement a simple e-commerce application to provide merchants with a more efficient order management method. Of course, this is just a basic example, and more functions and security need to be considered in actual applications. I hope this article is helpful to readers, thank you for reading! <\/p>"} </script>

<p>How to use PHP to implement a simple online order management system</p>
<p>1. Introduction</p>
<p>The online order management system is a common e-commerce application , which can help merchants effectively manage the order process, speed up order processing, and improve customer satisfaction. This article will introduce how to use PHP to implement a simple online order management system, including the creation, modification, query and deletion of orders. This article assumes that readers already have some basic knowledge of PHP. </p>
<p>2. System requirements</p>
<p>The online order management system needs to meet the following basic requirements:</p>
<ol>
<li>Login function: Administrators can log in to the system through username and password. </li>
<li>Order management function: Administrators can create, modify, query and delete orders. </li>
<li>Order list function: Administrators can view the list of orders, filter and sort by conditions. </li>
<li>Order details function: The administrator can view the detailed information of the order, including order number, customer information, product information, etc. </li>
<li>Database support: The system needs to use the MySQL database to store order data. </li>
</ol>
<p>3. Implementation steps</p>
<ol><li>Create database</li></ol>
<p>First, we need to create a database to store order data. Use the following SQL statement to create a database named "orders" and create a data table named "order_info" to store order information. </p><pre class='brush:php;toolbar:false;'>CREATE DATABASE orders;
USE orders;
CREATE TABLE order_info (
id INT(11) AUTO_INCREMENT PRIMARY KEY,
order_number VARCHAR(20) NOT NULL,
customer_name VARCHAR(50) NOT NULL,
total_price DECIMAL(10,2) NOT NULL,
create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);</pre><ol start="2"><li>Create a login page</li></ol><p>Create a file named "index.php" in the root directory of the project and add the following code: </p><pre class='brush:php;toolbar:false;'><?php
session_start();
if(isset($_POST['username']) && isset($_POST['password'])){
if($_POST['username'] === 'admin' && $_POST['password'] === 'admin'){
$_SESSION['login'] = true;
header('Location: order_list.php');
exit;
}

<p class="Articlelist_txts_p">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.</p>

<p class="Articlelist_txts_p">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.</p>

<p class="Articlelist_txts_p">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</p>

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.

<p class="Articlelist_txts_p">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.</p>

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.</p>
