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; // 默認(rèn)設(shè)置生成普通驗(yàn)證碼圖片 VerifyCode::getInstance()-> createCodeImg(); // 生成簡(jiǎn)單的計(jì)算驗(yàn)證碼圖片VerifyCode::getInstance()->createComputeCode(); // 如果你需要自定義參數(shù),可以傳入一個(gè)數(shù)組,例如: $baseConfig = [ 'width' => 130, // 圖片寬度'height' => 40, // 圖片高度'length' => 4, // 驗(yàn)證碼長(zhǎng)度'obstruction' => false, // 是否有干擾元素'onlyNumber' => false, // 是否只使用數(shù)字'textColor' => [50, 50, 255], // 文本顏色(RGB) 'backColor' => [255, 255, 255], // 背景顏色(RGB) 'font' => __DIR__ . '/basic.TTF', // 字體文件路徑'fontSize' => 20, // 字體大小'maxNumber' => 20, // 計(jì)算驗(yàn)證碼的最大數(shù)字]; // 使用自定義參數(shù)生成驗(yàn)證碼圖片VerifyCode::getInstance()->createCodeImg($baseConfig); VerifyCode::getInstance()->createComputeCode($baseConfig); // 驗(yàn)證用戶(hù)輸入的驗(yàn)證碼$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.

I'm having a tricky problem when doing a mail marketing campaign: how to efficiently create and send mail in HTML format. The traditional approach is to write code manually and send emails using an SMTP server, but this is not only time consuming, but also error-prone. After trying multiple solutions, I discovered DUWA.io, a simple and easy-to-use RESTAPI that helps me create and send HTML mail quickly. To further simplify the development process, I decided to use Composer to install and manage DUWA.io's PHP library - captaindoe/duwa.
