Talent recruitment is an important link in enterprise development. With the development of the Internet, more and more people of companies are beginning to adopt online talent recruitment systems to streamline the recruitment process and improve efficiency. In this article, we will introduce how to use PHP language to implement a simple online talent recruitment system and provide specific code examples.

1. Requirements Analysis

Before implementing the online talent recruitment system, it is first necessary to clarify the system requirements. A simple talent recruitment system usually includes the following functions:

User registration and login: Users can use the recruitment function by registering an account and logging in to the system.
Job Posting: Companies can post recruitment positions and provide detailed job descriptions and requirements.
Resume submission: Job seekers can browse the job list and select the position of interest to submit their resume.
Resume management: Enterprises can view received resumes, screen and manage them.

2. System design

Based on the above requirements, we can design the following system structure:

Database design: The system needs to design corresponding database tables To store user information, position information, resume information, etc. For example, the user table contains fields: username, password, email, etc.; the position table contains fields: position name, job description, salary, etc.; the resume table contains fields: user ID, position ID, job seeker information, etc.
Front-end design: Use front-end technologies such as HTML, CSS and JavaScript to design user interfaces, including user registration and login pages, job list pages, job details pages, etc.
Back-end design: Use PHP language to process user requests and implement system functions. For example, the user registration and login function can use PHP to verify the entered user name and password; the job posting function can use PHP to save data into the database; the resume delivery function can use PHP to obtain the position ID selected by the user and save it to the resume table Medium; the resume management function can use PHP to query the database and display received resumes, etc.

3. Code Implementation

The following is a simple code example to demonstrate how to use PHP to implement the user registration function in the talent recruitment system:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "root", "", "recruitment_system");

// 处理用户提交的注册表单
if(isset($_POST['submit'])) {
    $username = $_POST['username'];
    $password = $_POST['password'];
    $email = $_POST['email'];

    // 验证用户名是否已存在
    $query = "SELECT * FROM users WHERE username = '$username'";
    $result = mysqli_query($conn, $query);
    if(mysqli_num_rows($result) > 0) {
        echo "用户名已存在，请重新输入";
    } else {
        // 将用户信息插入数据库
        $query = "INSERT INTO users (username, password, email) VALUES ('$username', '$password', '$email')";
        mysqli_query($conn, $query);

        echo "注册成功";
    }
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>用户注册</title>
</head>
<body>
    <h2>用户注册</h2>
    <form method="post" action="">
        <label>用户名</label>
        <input type="text" name="username" required><br>

        <label>密码</label>
        <input type="password" name="password" required><br>

        <label>邮箱</label>
        <input type="email" name="email" required><br>

        <input type="submit" name="submit" value="注册">
    </form>
</body>
</html>

The above code obtains and inserts the registration form data submitted by the user into the database, realizing the user registration function.

4. Summary

This article introduces how to use PHP language to implement a simple online talent recruitment system, including user registration and login, job posting, resume delivery and resume management functions. Through the analysis of the design system structure and specific code examples, I hope readers can understand and master how to use PHP to develop an online talent recruitment system, and be able to expand and optimize functions according to actual needs.
