A simple implementation method of thinkPHP3.1 verification code, thinkphp3.1 verification code

The example in this article describes a simple implementation method of thinkPHP3.1 verification code. Share it with everyone for your reference, the details are as follows:

Write in the code:

public function verify(){
    import('ORG.Util.Image');
    ob_clean();
    Image::buildImageVerify();
}

Write in html:

<img src='__APP__/Index/verify/'
  onClick="this.src=this.src+'&#63;'+Math.random()"
/>

That is to say, the path of the image is the access path of the above php code, and it is ok

If the image is not displayed, it is ob_clean(); it is not written. This method is to remove the cache and so on

If it is garbled, just write the above php code directly in front of the display method. Remember, this method is separate and should not be mixed with other methods
