Second, the assignment route and the reference of CAPTCHA

1) assign a route first (each reference address must be assigned to each route)

After the creation is successful, see if you can successfully access the

2) reference a third-party library (under the recource folder, org represents)

3) load class require_once'.. / resources/org/code/Code.class.php' in controller

Session_start (); the laravel framework itself encapsulates session. Native session may be used when referencing extension classes, and the entry file index.php is opened.

Require_once'.. / resources/org/code/Code.class.php'; / / include the class first, and the actual path will be modified according to the actual situation. $code = new Code (); / / instantiate an object $code- > doimg (); $_ SESSION ['code'] = $code- > getCode (); / / Save the CAPTCHA to SESSION
