What's Covered

51Degrees device detector returns all detection results as a string. This tutorial demonstrates how to return results for the IsMobile property value as a boolean.

Code and Explanation

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 = FiftyOneDegreesTrieV3::provider_get();

  • Produce a match for a single HTTP User-Agent header 

    									
my $match = $provider->getMatch($userAgent)
  • Extract the value of the IsMobile property as a boolean 

    									
if ($match->getValue('IsMobile') == "True") {
	return TRUE;
}
else {
	return FALSE;
}
    This example assumes you have the 51Degrees PHP API installed correctly, and have FiftyOneDegreesTrieV3.php in this directory.

    • Summary

    In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined User-Agent string. It sets a boolean value to true or false from the original string value of "True" or "False", making if statements simpler to test.
