Cort, you never told me if you wanted a version that could check against multiple os'es as well, so:

if anyone needs a version that can check multiple os'es at a time (IE something like

<if condition="is_os('XXX', 'YYY', 'ZZZ')">
Insert Code Here
</if>

for various reasons, like plugins/code working on several os'es), the code would be this:

PHP Code:

// #################### Start is os ##########################
// os detection script
function is_os()
{
    $os = func_get_args();
    
    $useragent = strtolower($_SERVER['HTTP_USER_AGENT']);

    // detect windows
    if ((strpos($useragent, 'winnt') !== false) OR (strpos($useragent, 'win32') !== false) OR (strpos($useragent, 'windows') !== false))
    {
        $found_os = 'windows';
    }
        
    // detect macintosh
    if (strpos($useragent, 'mac') !== false)
    {
        $found_os = 'mac';
    }

    // detect linux
    if ((strpos($useragent, 'linux') !== false) OR (strpos($useragent, 'x11') !== false) OR (strpos($useragent, 'i686') !== false))
    {
        $found_os = 'linux';
    }

    // detect web tv
    if (strpos($useragent, 'webtv') !== false)
    {
        $found_os = 'webtv';
    }

    // sanitize the incoming os names
    foreach ($os as $ops)
    {
        $opsys[] = strtolower($ops);
    }
    if (in_array($found_os, $opsys))
    {
        return true;
    }
    else
    {
        return false;
    }
}
// #################### End is os ########################## 


The difference is that if you want your code to be executed on both f.ex. linux and windows, you would have to use

<if condition="is_os('windows') OR is_os('linux')">
Insert Code Here
</if>
