note 32401 modified in function.version-compare by cellog

The examples given all assume the version numbers consist of exactly three integers. This, however, is not a strict rule. version_compare() will work correctly when the version numbering goes down to deeper levels, and also when the levels between the two versions being compared differ. So 1.2 will correctly be shown to be a higher version than 1.1.9.8 which in turn is higher than 1.1.9.7. In addition, if a level contains a non-numeric character, then a string comparison is performed on that level rather than a numeric comparison. I don't know what the limits are, but it looks to be broad enough to use in most practical situations. I've tested this on PHP 4.1.2. --was-- The examples given all assume the version numbers consist of exactly three integers.
