A lightweight PHP class for detecting mobile devices and tablets using User-Agent strings and HTTP headers.
Mobile Detect is a lightweight PHP library that identifies mobile devices, including tablets, by analyzing the User-Agent string and specific HTTP headers. It enables developers to detect device types and capabilities to optimize web experiences for mobile users. The library is designed as a minimal, efficient class with no external dependencies.
PHP developers building web applications that require server-side detection of mobile and tablet devices to deliver optimized content or redirect users. It is also suitable for projects needing a simple, dependency-free solution for device detection.
Developers choose Mobile Detect for its simplicity, reliability, and lack of external dependencies, making it easy to integrate into PHP projects. It offers maintained support for multiple PHP versions, with a current recommended version for PHP 8+, and provides specific tablet detection alongside general mobile device identification.
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.

The library is a single PHP class with no external dependencies, making integration straightforward and avoiding conflicts in any project, as highlighted in the philosophy.
Maintained branches support PHP versions from 5.0 to 8.0+, with the 4.8.x version recommended for PHP 8+, ensuring compatibility across legacy and modern systems, as shown in the version table.
Explicitly distinguishes tablets from other mobile devices, a key feature for optimizing layouts, which is often missing in basic detection libraries.
The project provides detailed documentation on Gitbook and a live demo, helping developers quickly implement and test detection logic, as referenced in the README.
Detection relies on parsing User-Agent strings, which are increasingly spoofed or minimized for privacy, leading to potential inaccuracies with modern browsers and requiring regular updates.
The library has multiple versions with different namespaces (e.g., \Mobile_Detect vs \Detection\MobileDetect) and deprecated branches, complicating upgrades and integration, as noted in the version table.
It only identifies device types (mobile/tablet) and not browser capabilities or screen dimensions, which might necessitate additional libraries for comprehensive responsive design.
Analyzing User-Agent strings on every request can add CPU overhead, which may be significant for high-traffic applications without implementing caching strategies.
