@entertain:
May I suggest to use the following function to compare version strings?

function itrader_CompareVersions($verstr1, $verstr2)
{
	$ver1 = explode('.', $verstr1);
	$ver2 = explode('.', $verstr2);
	for($i = 0; $i < 3; $i++)
	{
		if(intval($ver1[$i]) > intval($ver2[$i]))
			return -1;
		elseif(intval($ver1[$i]) < intval($ver2[$i]))
			return 1;
	}
	return 0;
}

The function will return 1 if verstr1 > verstr2, -1 if verstr1 < verstr2 and 0 if they are equal.
