FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

更多说明

如果创建验证码时使用独立的key

ThinkCaptcha::printImg('test') // 'test'是识别key,限数字和字母

那么验证时也需要传入同名key

ThinkCaptcha::check($code,'test') // 'test'是识别key,限数字和字母

默认验证完后不论成功还是错误都会删除验证码数据，如果验证完后不删除

ThinkCaptcha::check($code,'test',0) // 0表示不删除

或者，只有在验证成功后才删除

ThinkCaptcha::check($code,'test',1) // 1表示验证成功后才删除

当然，验证时也可以设置验证码过期时间，默认1800秒(30分钟内有效)

ThinkCaptcha::check($code,'test',2,3600) // 1小时内有效

独立配置

配置文件中提供独立配置，

如果无效果建议将配置文件config.php改名为phpu_captcha.php移入项目配置目录内！

使用configure()配置，参数是配置文件一级数组的索引，默认为default
