The simplest way to generate a verification code:

(1) We still continue to write in that controller Method

This method displays the page of this verification code

public function xianshi()
{
    $this->show();  
}

public function shengcheng()
{
    //造验证码的对象
    $v = new \Think\Verify();
    //生成验证码
    $v->entry();
}

(2) The page that displays the verification code should still be placed in , name it

<img  src="/static/imghw/default1.png"  data-src="__CONTROLLER__/shengcheng"  class="lazy"   / alt="How to set the width and height of thinkphp verification code" >

Run it and see the results:

(3) We can also set the size for it, and every time the page is refreshed, The verification code will change.

Just give him an attribute, for example:

<img  src="/static/imghw/default1.png"  data-src="__CONTROLLER__/shengcheng"  class="lazy"      style="max-width:90%"  style="max-width:90%" / alt="How to set the width and height of thinkphp verification code" >

Both width and height become larger

$config = array(   
    'fontSize'    =>    30,    // 验证码字体大小   
    'length'      =>    3,     // 验证码位数   
    'useNoise'    =>    false, // 关闭验证码杂点
);
$Verify = new \Think\Verify($config);
$Verify->entry();
