List of user-agent strings
Some quick notes on the user-agent strings.
A user-agent string is a string sent in every HTTP request by client applications to servers. A string that includes useful information about the type and version of browser, operating system, language. The user-agent is a form of identification of an HTTP client, this still-identification - can be modified and altered to provide information (for example, through add-on for Firefox or other solutions).
There are many sites that offer lists of user-agent strings, some of these easily accessible and up to date are:

Our simple to use with PHP / CURL (excerpt):
$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => selectUseragent(), // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
);
$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
