PHP Study Notes: Human Resource Management and Recruitment System
Human resource management plays a vital role in modern enterprises. With the development of technology, many companies are turning to information technology to manage their human resources. As a popular server-side scripting language, PHP is widely used to develop various enterprise application systems, including human resources management and recruitment systems. This article will introduce how to use PHP to develop a simple human resources management and recruitment system, and provide some specific code examples.
- Create database
First, we need to create a database to store employee and job applicant information. MySQL or other relational databases can be used. Here is an example of creating an employee table and an applicant table:
CREATE TABLE employees ( id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(50) NOT NULL, email VARCHAR(50) NOT NULL, position VARCHAR(50) NOT NULL ); CREATE TABLE applicants ( id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(50) NOT NULL, email VARCHAR(50) NOT NULL, position VARCHAR(50) NOT NULL, resume TEXT NOT NULL );
- Connecting to the database
Connecting to the database using PHP is very simple. Here is an example of connecting to a MySQL database:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "hr_management";
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检查连接是否成功
if ($conn->connect_error) {
die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
?>- Add employees and applicants
Here is an example code to add employee and applicant records to the database :
<?php
// 处理添加员工的请求
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["add_employee"])) {
$name = $_POST["name"];
$email = $_POST["email"];
$position = $_POST["position"];
// 插入记录到员工表
$sql = "INSERT INTO employees (name, email, position) VALUES ('$name', '$email', '$position')";
if ($conn->query($sql) === TRUE) {
echo "添加员工成功";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
// 处理添加求职者的请求
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["add_applicant"])) {
$name = $_POST["name"];
$email = $_POST["email"];
$position = $_POST["position"];
$resume = $_POST["resume"];
// 插入记录到求职者表
$sql = "INSERT INTO applicants (name, email, position, resume) VALUES ('$name', '$email', '$position', '$resume')";
if ($conn->query($sql) === TRUE) {
echo "添加求职者成功";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
?>- Recruitment management page
The following is a sample code for a simple recruitment management page:
<!DOCTYPE html>
<html>
<head>
<title>招聘管理</title>
</head>
<body>
<h1 id="招聘管理">招聘管理</h1>
<h2 id="添加员工">添加员工</h2>
<form method="POST" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
<input type="text" name="name" placeholder="姓名" required>
<input type="email" name="email" placeholder="电子邮箱" required>
<input type="text" name="position" placeholder="职位" required>
<button type="submit" name="add_employee">添加员工</button>
</form>
<h2 id="添加求职者">添加求职者</h2>
<form method="POST" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
<input type="text" name="name" placeholder="姓名" required>
<input type="email" name="email" placeholder="电子邮箱" required>
<input type="text" name="position" placeholder="期望职位" required>
<textarea name="resume" placeholder="简历" required></textarea>
<button type="submit" name="add_applicant">添加求职者</button>
</form>
</body>
</html>Through the above steps, we have established A simple HR management and recruitment system that adds employee and applicant records and saves them to a database. Of course, this is just a simple example, and a real human resources management system may require more functions and pages.
Summary
This article briefly introduces how to use PHP to develop a simple human resources management and recruitment system. We learned how to create a database, connect to the database, and add employee and applicant records. Of course, the actual system may require more functions, such as viewing and editing records. I hope this article will be helpful to you in the process of learning PHP.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
