think-captcha

thinkphp5 verification code library

Install

composer require topthink/think-captcha

use

Output the verification code in the template

<div>{:captcha_img()}</div>

or

<div><img src="//m.sbmmt.com/m/xiazai/leiku/{:captcha_src()}" alt="captcha" /></div>

上面两种的最终效果是一样的

Verify in the controller

Just use TP5’s built-in verification feature

$this->validate($data,[
    'captcha|验证码'=>'require|captcha'
]);

Or verify manually

if(!captcha_check($captcha)){
 //验证失败
};
