Local parser is very fast and accurate useragent string detection solution. Enables developers to locally install and integrate a highly-scalable product. We provide the detection of the devices (personal computer, tablet, Smart TV, Game console etc.), operating system, client SW type (browser, e-mail client etc.) and devices market name (example: Sony Xperia Tablet S, Nokia Lumia 820 etc.).

// enable/disable LRU cache
$parser->setCacheEnable(false); // default is enable
//$parser->setCacheSize(4000);  // default size is 3000

try {   
    $parser->setSecChUa('"Chromium";v="104", " Not A;Brand";v="99", "Google Chrome";v="104"');
