Generate User-Agent strings, roughly based on browser and OS usage statistics.

Numbers for more minor variable components of the User-Agent for each browser are chosen randomly, so it may at times generate User-Agents that never actually exist in the wild.

Simply require uagent.php and call the function UAgent::random(). You may optionally pass a single parameter consisting of an array of language codes to randomly choose from.

• Chrome
• Firefox: Gecko User Agent String Reference
• Internet Explorer: Understanding User-Agent Strings
• Safari
• Opera: Opera User Agent Strings: Opera 15 and Beyond

Generated User-Agent strings are based on formats of valid User-Agents found in the wild but minor variable components such as version numbers aren't always REAL(TM), but they should be well-formed and therefore look realistic.
