51Degrees Device Detection On-Premise PHP  4.4

Device detection services for 51Degrees Pipeline


This example shows how to use 51Degrees on-premise device detection to determine details about a device based on its User-Agent and User-Agent Client Hint HTTP header values.

You will learn:

  1. How to create a Pipeline that uses 51Degrees on-premise device detection
  2. How to pass input data (evidence) to the Pipeline
  3. How to retrieve the results

This example is available in full on GitHub.

This example requires a local data file. The free 'Lite' data file can be acquired by pulling the git submodules under this repository (run `git submodule update --recursive`) or from the device-detection-data GitHub repository.

The Lite data file is only used for illustration, and has limited accuracy and capabilities. Find out about the more capable data files that are available on our pricing page
