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.

Informations about the package captcha

验证码组件

安全可靠的验证码,拥有很强的反机器识别能力,同时又不失人眼阅读体验。

吐槽一下,这个验证码我最新发布在 PHPChina 论坛,后来2009年9月我转发到了javaeye。现在有很多PHP图片验证码都是抄袭自这里,然后堂而皇之的改版权,比如 ThinkPHP 的 think-captcha

当前大数据横行的年代,这种图片验证码已经过时,图片扭曲到很难看清,干扰信息加上一大堆,机器识别率都能到百分之八九十。 推荐使用短信、邮箱验证码 + 登录限流。 注册可以用交互式验证码 + 限流,如选中文(出两三个扭曲中文,让用户从扭曲旋转文字的九宫格中按顺序选出对应的字),滑动验证码、旋转验证码等。

require

安装

该组件已包含在Windwork框架中,如果你已安装Windwork框架则可以直接使用。
