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

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();
```
Produce a match for a single HTTP User-Agent header
```
my $match = $provider->getMatch($userAgent)
```
Extract the value of the IsMobile property
```
$match->getValue('IsMobile')
```
Obtain device Id: consists of four components separated by a hyphen symbol: Hardware-Platform-Browser-IsCrawler where each Component represents an ID of the corresponding Profile.
```
$match->getDeviceId();
```
Obtain match method: provides information about the algorithm that was used to perform detection for a particular User-Agent. For more information on what each method means please see: How device detection works
```
$match->getMethod();
```
Obtain difference: used when detection method is not Exact or None. This is an integer value and the larger the value the less confident the detector is in this result.
```
$match->getDifference();
```
Obtain signature rank: an integer value that indicates how popular the device is. The lower the rank the more popular the signature.
```
$match->getRank();
```

This example assumes you have the 51Degrees PHP API installed correctly, and have FiftyOneDegreesPatternV3.php in this directory. */ // Snippet Start 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) ".
