51Degrees Device Detection On-Premise PHP  4.2

Device detection services for 51Degrees Pipeline

hash/failureToMatch.php

This example shows how the hasValue function can help make sure that meaningful values are returned when checking properties returned from the device detection engine.This example is available in full on GitHub.

In this example we create an on premise 51Degrees device detection pipeline, in order to do this you will need a copy of the 51Degrees on-premise library and need to make the following additions to your php.ini file

FiftyOneDegreesHashEngine.data_file = // location of the data file
FiftyOneDegreesHashEngine.allow_unmatched = false

Expected output:

Does User-Agent 'Mozilla/5.0 (iPhone; CPU iPhone OS 11_2 like Mac OS X) AppleWebKit/604.4.7 (KHTML, like Gecko) Mobile/15C114' represent a mobile device?:
Yes
Does User-Agent 'nonsense ua...' represent a mobile device?:
We don't know for sure. The reason given is:
The results contained a null profile for the component which the required property belongs to.
