These pages show you how to set up and use the 51Degrees device detection API. For more information on how device detection works and can benefit you, please visit our Device Detection Page .

Getting started example of using 51Degrees device detection. The example shows how to:

1. Fetch a pointer to the 51Degrees device detection provider instance. This is instantiated on server startup and uses settings from php.ini.

   										
   $provider = FiftyOneDegreesPatternV3::provider_get();
   
   										

2. Produce a match for a single HTTP User-Agent header

   										
   my $match = $provider->getMatch($userAgent)
   
   										

3. Extract the value of the IsMobile property

   										
   $match->getValue('IsMobile')
   
   										

										
require("../pattern/FiftyOneDegreesPatternV3.php");

$provider = FiftyOneDegreesPatternV3::provider_get();

// User-Agent string of an iPhone mobile device.
$mobileUserAgent = "Mozilla/5.0 (iPhone; CPU iPhone OS 7_1 like Mac OS X) ".
"AppleWebKit/537.51.2 (KHTML, like Gecko) 'Version/7.0 Mobile/11D167 ".
"Safari/9537.53";

// User-Agent string of Firefox Web browser version 41 on desktop.
$desktopUserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:41.0) ".
"Gecko/20100101 Firefox/41.0";

// User-Agent string of a MediaHub device.
$mediaHubUserAgent = "Mozilla/5.0 (Linux; Android 4.4.2; X7 Quad Core ".
"Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 ".
"Chrome/30.0.0.0 Safari/537.36";

echo "Starting Getting Started Example.<br>\n";

// Carries out a match with a mobile User-Agent.
echo "<br>\nMobile User-Agent: ".$mobileUserAgent."<br>\n";
$match = $provider->getMatch($mobileUserAgent);
echo "IsMobile: ".$match->getValue("IsMobile")."<br>\n";

// Carries out a match with a desktop User-Agent.
echo "<br>\nDesktop User-Agent: ".$desktopUserAgent."<br>\n";
$match = $provider->getMatch($desktopUserAgent);
echo "IsMobile: ".$match->getValue("IsMobile")."<br>\n";

// Carries out a match with a MediaHub User-Agent.
echo "<br>\nMediaHub User-Agent: ".$mediaHubUserAgent."<br>\n";
$match = $provider->getMatch($mediaHubUserAgent);
echo "IsMobile: ".$match->getValue("IsMobile")."<br>\n";


										

For more examples see the tutorial pages.

51Degrees device detection implementation does not rely on regular expressions, instead our algorithm looks at character positions in the HTTP User-Agent string and picks a set of signatures that represents the closest match. Then a set of four profiles (one for each of the following components: hardware, software, browser and crawler) is derived from those signatures. Properties and the corresponding values are then derived from those profiles. For more information and examples please see the How Device Detection Works  page.
