What is PHP Device Detector?
51Degrees Device Detector for PHP provides intelligence about the device, operating system and browser accessing a web site at run time enabling developers and designers to adapt the initial response from the server. Existing web sites can be converted to support mobile devices quickly. The solution can be combined with emerging methodologies such as responsive design or progressive enhancement to produce great results quickly.
When a HTTP request is received, 51Degrees must find a matching device from the database. The logic used to achieve this is shared across other implementation and is fully described in the how device detection works pages.
The matched device is stored in the session if available to avoid the need to repeat this process for subsequent requests.
