Easily implement verification code function: Use Composer to install the lsmverify/lsmverify library

Composer can be learned through the following address: Learning address

During the development process, I found that the traditional verification code generation method is either not safe enough or is too complicated to implement. The lsmverify/lsmverify library provides a simple and easy-to-use API that can quickly generate various types of verification codes, including ordinary verification codes and computed verification codes. Here are the detailed steps to install and use this library using Composer:

Install lsmverify/lsmverify

Installing this library is very simple, just run the following Composer command in the root directory of your project:

 <code class="bash">composer require lsmverify/lsmverify</code>

If your project has not installed Composer, you can click here to download and install it.

Use the lsmverify/lsmverify library

After the installation is complete, you can use this library in your PHP code as follows:

 <code class="php"><?php require_once ('../vendor/autoload.php');
use LsmVerify\Verify\VerifyCode;

// 默认设置生成普通验证码图片
VerifyCode::getInstance()-> createCodeImg(); // 生成简单的计算验证码图片VerifyCode::getInstance()->createComputeCode(); // 如果你需要自定义参数，可以传入一个数组，例如： $baseConfig = [ 'width' => 130, // 图片宽度'height' => 40, // 图片高度'length' => 4, // 验证码长度'obstruction' => false, // 是否有干扰元素'onlyNumber' => false, // 是否只使用数字'textColor' => [50, 50, 255], // 文本颜色（RGB） 'backColor' => [255, 255, 255], // 背景颜色（RGB） 'font' => __DIR__ . '/basic.TTF', // 字体文件路径'fontSize' => 20, // 字体大小'maxNumber' => 20, // 计算验证码的最大数字]; // 使用自定义参数生成验证码图片VerifyCode::getInstance()->createCodeImg($baseConfig); VerifyCode::getInstance()->createComputeCode($baseConfig); // 验证用户输入的验证码$code = '1234'; $result = VerifyCode::getInstance()->checkCode($code); // checkCode 方法返回true 或false</code>

By using the lsmverify/lsmverify library, I not only successfully implemented efficient verification code functions in the project, but also greatly reduced development time and maintenance costs. The advantage of this library is its simplicity and high configurability. It can generate different types of verification codes according to project requirements, thereby effectively preventing robot attacks and improving system security.

In general, Composer, as a dependency management tool for PHP, greatly simplifies the installation and management process of external libraries. Installing the lsmverify/lsmverify library through Composer, I not only solved the problem of verification code generation, but also experienced the powerful functions and convenience of Composer in project development. If you encounter similar problems in development, you might as well try this method.
