how to get current locale in PHP

Question

I would like to get the current system locale of a server (say windows 7 os). This is to ensure that different language setting uses different parts of code in PHP.
However, I could not find any API that does this.
Can anyone tell me the name of the function?

Getting the local information from PHP is going to be near impossible, you will need Javascript which runs on the client machine. Then you can pass that to PHP — Daniel Casserly

Having thought more about the problem and the particular setup I have, I came up with this solution, which seems to work. Note that I don't have control over what languages I need to support: there are translation files dropped into a predefined place and system locales installed by someone else. During runtime, I need to support a particular language if corresponding translation file exists and and system locale is installed. This got me to this solution:

Use below function

function getLocale($lang)
{
    $locs = array();
    exec('locale -a', $locs);

    $locale = 'en-IN';
    foreach($locs as $l)
    {
        $regex = "/$lang\_[A-Z]{2}$/";
        if(preg_match($regex, $l) && file_exists(TRANSROOT . "/$lang.php"))
        {
            $locale = $l;
            break;
        }
    }

    return $locale;
}

I'm defaulting to en-IN if I cannot resolve a locale, because I know for certain that en-IN is installed.
