Using devkeep/tools PHP Package: Installation, Utility Functions, and Example Usage

During development, repetitive data handling logic can lead to duplicated code; this article introduces the open‑source devkeep/tools package for PHP, which provides a collection of utility functions to streamline such tasks.

Installation

composer require devkeep/tools

Utility functions include object‑to‑array conversion, tree categorization, multi‑dimensional array deduplication and sorting, number formatting, HTTP GET/POST requests, array‑XML conversion, zip creation/extraction, file download, email sending, Excel export, and QR code generation. The functions are accessed via devkeep\Tools\Tools::functionName() .

Example usage

// Keep two decimal places
$res = devkeep\Tools\Tools::format(100, 2);

// Multi‑dimensional array sorting
$res = devkeep\Tools\Tools::arrayMultiSort([
    ['id' => 1],
    ['id' => 2],
    ['id' => 3],
], 'id', 'desc');

// Tree classification (non‑recursive)
$res = devkeep\Tools\Tools::tree([
    ['id' => 1, 'pid' => 0, 'title' => 'title'],
    ['id' => 3, 'pid' => 1, 'title' => 'title3'],
    ['id' => 4, 'pid' => 1, 'title' => 'title4'],
]);

// Export Excel
devkeep\Tools\Tools::exportExcel(['标题','价格','重量'], [
    ['标题一','1.00','1KG'],
    ['标题二','2.00','2KG'],
], 'abc');

// Generate QR code
devkeep\Tools\Tools::qrcode('http://www.baidu.com', false, 'L', 6, 2);

// Send email
$res = devkeep\Tools\Tools::sendMail([
    'host' => 'smtp.aliyun.com',
    'port' => 465,
    'username' => '[email protected]',
    'password' => 'xxxx',
    'address' => '[email protected]',
    'title' => '测试邮件',
], [
    'mail' => '[email protected]',
    'name' => '张三',
    'subject' => '主题',
    'body' => '这是一个邮件',
]);
var_dump($res);

The article encourages readers to download the package, test it in their own projects, and adapt the code to fit their specific needs.
