Intervention.io is the home of the high-quality open‑source PHP libraries created by Oliver Vogel, a European software developer. The website serves as a central hub for the documentation of the libraries, published under the Intervention vendor namespace.
Oliver became known in 2013 for his work on the widely used Intervention Image Library, and in the following years he started other open source releases, mainly in the PHP world.
With the rise of Laravel from this point on, projects were created that complemented and were inspired by the framework. This led to the creation of Intervention Validation, which provides a large number of important validation rules that the framework does not natively support.
In the early days of Laravel, a library was also ported whose functionality was not yet part of the framework. Intervention HttpAuth provides authentication management with HTTP Basic or Digest authentication. Intervention Zodiac was also added, a library that allows the calculation of astrological signs.
The main work of Intervention at the moment is the further development of the Image Library, which is currently one of the most used PHP packages and has been installed almost 160 million times.
One goal of the development work is always to provide an easily accessible API with a flat learning curve. The developer should not have to struggle with complicated configuration routines or get lost in complex architecture, but should be able to get the job done quickly and easily.
