Use of asset depreciation function developed by PHP in enterprise resource planning (ERP) system

The use of the asset depreciation function developed by PHP in the enterprise resource planning (ERP) system

Introduction:
In the process of business operation, asset depreciation is an important financial concept. Asset depreciation refers to the process of reducing the value of an asset due to the reduction in its useful life during use. In enterprise resource planning (ERP) systems, the development of asset depreciation functions is critical to achieving automation and accuracy in financial management. This article will explore how to use PHP to develop asset depreciation functions, and attach corresponding code examples.

1. The concept and method of asset depreciation
Asset depreciation refers to the process by which enterprises reduce the value of long-term assets by a certain proportion or method to reflect their consumption and gradual reduction in service life. Common asset depreciation methods include straight-line method, accelerated depreciation method, and reduced residual value method.

1. Straight-line method:
   The straight-line method is the most commonly used method of asset depreciation, which assumes that the value of long-term assets decreases uniformly over its useful life. The formula for calculating depreciation is: depreciation = (original value of asset - estimated residual value) / useful life.
2. Accelerated depreciation method:
   The accelerated depreciation method is based on the rapid decline in value of assets in the early stages of use. The depreciation amount is increased in the first few years and is relatively low in the following years. Common accelerated depreciation methods include double declining balance method (DB-M) and triple declining balance method (TB-M).
3. Deduction of residual price method:
   Deduction of residual price method refers to depreciation based on the net residual value of the asset during the entire service life of the asset. The depreciation amount will gradually decrease with the actual depreciation each year.

2. PHP development asset depreciation function code example

<?php
// 资产折旧功能函数
function calculateDepreciation($originalValue, $expectedResidualValue, $life){
    $depreciation = ($originalValue - $expectedResidualValue) / $life;
    return $depreciation;
}

// 直线法折旧计算示例
$originalValue = 10000; // 资产原值
$expectedResidualValue = 2000; // 预计残值
$life = 5; // 使用寿命

$depreciation = calculateDepreciation($originalValue, $expectedResidualValue, $life);

echo "直线法折旧额：".$depreciation;

// 加速折旧法折旧计算示例
$originalValue = 10000; // 资产原值
$expectedResidualValue = 2000; // 预计残值
$life = 5; // 使用寿命

$accumulatedDepreciation = 0;
for($year = 1; $year <= $life; $year++){
    $depreciation = $originalValue * (2/$life);
    $accumulatedDepreciation += $depreciation;
    $originalValue -= $depreciation;
    echo "第".$year."年的折旧额：".$depreciation."
";
}
echo "累计折旧额：".$accumulatedDepreciation;

// 减余价法折旧计算示例
$originalValue = 10000; // 资产原值
$expectedResidualValue = 2000; // 预计残值
$life = 5; // 使用寿命

$accumulatedDepreciation = 0;
for($year = 1; $year <= $life; $year++){
    $depreciation = ($originalValue - $accumulatedDepreciation) * (1/$life);
    $accumulatedDepreciation += $depreciation;
    echo "第".$year."年的折旧额：".$depreciation."
";
}
echo "累计折旧额：".$accumulatedDepreciation;
?>

The above code example demonstrates the calculation process of different depreciation methods and outputs the relevant results. During the actual development process, you can perform secondary development according to your needs and add more parameters and functions to meet the actual needs of the enterprise.

Conclusion:
The asset depreciation function developed by PHP has important application value in the enterprise resource planning (ERP) system. By using the PHP programming language, we can realize automated calculation and management of asset depreciation and improve the accuracy and efficiency of financial management. I hope that the asset depreciation function code examples provided in this article will be helpful to you when developing your ERP system.
