Mobile Detect

Motto: "Every business should have a mobile detection script to detect mobile readers."

Mobile_Detect is a lightweight PHP class for detecting mobile devices (including tablets). It uses the User-Agent string combined with specific HTTP headers to detect the mobile environment.

We're committed to make Mobile_Detect the best open-source mobile detection resource and this is why before each release we're running unit tests, we also research and update the detection rules on daily and weekly basis.

Your website's content strategy is important! You need a complete toolkit to deliver an experience that is optimized, fast and relevant to your users. Mobile_Detect class is a server-side detection tool that can help you with your RWD strategy, it is not a replacement for CSS3 media queries or other forms of client-side feature detection.
