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.
Please rate this library. Is it a good library?

Synopsis

See the example form to get started. PHP sessions are not required if database storage is used instead.

Description

What is Securimage?

Securimage is a PHP class that is used to generate and validate CAPTCHA images.

The classes uses an existing PHP session or creates its own if none is found to store the CAPTCHA code. In addition, a database can be used instead of session storage.

Variables within the class are used to control the style and display of the image. The class uses TTF fonts and effects for strengthening the security of the image.

It also creates audible codes which are played for visually impared users.

UPGRADE NOTICE

3.6.3 and below: Securimage 3.6.4 fixed a XSS vulnerability in example_form.ajax.php. It is recommended to upgrade to the latest version or delete example_form.ajax.php from the securimage directory on your website.

3.6.2 and above:

If you are upgrading to 3.6.2 or greater AND are using database storage, the table structure has changed in 3.6.2 adding an audio_data column for storing audio files in the database in order to support HTTP range requests. Delete your tables and have Securimage recreate them or see the function createDatabaseTables() in securimage.php for the new structure depending on which database backend you are using and alter the tables as needed. If using SQLite, just overwrite your existing securimage.sq3 file with the one from this release.

If you are not using database tables for storage, ignore this notice.
