Application of payroll accounting function developed using PHP in enterprise resource planning (ERP) system

With the expansion of enterprise scale and the complexity of payroll management, many companies have begun to realize the importance of payroll accounting functions sex. To increase efficiency and reduce errors, many businesses choose to integrate payroll functionality into their enterprise resource planning (ERP) systems. This article will introduce how to use PHP to develop payroll accounting functions and demonstrate its application in ERP systems.

First of all, we need to establish a database with payroll accounting function. We can create a database named "salary", which contains employee information, salary and other related tables. Below is a sample code for creating a database and related tables:

// 创建数据库
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "salary";

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

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

$sql = "CREATE DATABASE ".$dbname;
if ($conn->query($sql) === TRUE) {
    echo "Database created successfully";
} else {
    echo "Error creating database: " . $conn->error;
}

$conn->close();

// 创建员工表格
$conn = new mysqli($servername, $username, $password, $dbname);

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

$sql = "CREATE TABLE employees (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(30) NOT NULL,
    salary FLOAT(10,2) NOT NULL,
    position VARCHAR(30) NOT NULL
)";

if ($conn->query($sql) === TRUE) {
    echo "Table employees created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

$conn->close();

// 创建工资表格
$conn = new mysqli($servername, $username, $password, $dbname);

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

$sql = "CREATE TABLE salary (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    employee_id INT(6) NOT NULL,
    year INT(4) NOT NULL,
    month INT(2) NOT NULL,
    salary FLOAT(10,2) NOT NULL,
    FOREIGN KEY (employee_id) REFERENCES employees(id)
)";

if ($conn->query($sql) === TRUE) {
    echo "Table salary created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

$conn->close();

The above code will create a database named "salary" and create two tables in the database: "employees" and "salary" . The "employees" table contains employee information, and the "salary" table contains employee salary information. Next, we can use PHP to develop the payroll accounting function for use in the ERP system.

First, we need to create a salary calculation function to calculate salary based on employee's salary, attendance and other information. The following is a sample code:

function calculateSalary($employee_id, $year, $month) {
    // 根据员工id和时间查询薪资相关信息
    $sql = "SELECT * FROM employees WHERE id = ".$employee_id;
    $result = $conn->query($sql);
    $employee = $result->fetch_assoc();
    
    // 进行薪资计算
    $salary = $employee["salary"];
    
    // 将计算结果保存到数据库中
    $sql = "INSERT INTO salary (employee_id, year, month, salary) VALUES (".$employee_id.", ".$year.", ".$month.", ".$salary.")";
    $conn->query($sql);
    
    // 返回计算结果
    return $salary;
}

The above code first queries the employee's relevant information based on the employee ID and time, then calculates the salary, and saves the calculation results to the database. Finally, the calculation result is returned.

In the ERP system, we can perform salary calculation by calling the above function. The following is a sample code for salary calculation in the ERP system:

// 呼叫薪资核算函数
$employee_id = 1;
$year = 2021;
$month = 10;
$salary = calculateSalary($employee_id, $year, $month);

echo "员工".$employee_id."在".$year."年".$month."月的薪资为".$salary."元。";

The above code first calls the salary calculation function, and then prints out the calculation results.

To sum up, using the salary accounting function developed in PHP can realize the calculation and management of employee salaries in the enterprise resource planning (ERP) system. By establishing relevant databases and tables and writing corresponding codes, we can easily perform salary calculations and save the results to the database. The application of payroll accounting functions can improve the efficiency of an enterprise's payroll management and reduce the occurrence of errors.
