int version_compare(string one, string two[, string operator])

Compares two strings of the format “4.1.0” and returns -1 if one is less than two, 0 if they are equal, and 1 if one is greater than two. If operator is specified, the operator is used to make a comparison between the version strings, and the value of the comparison using that operator is returned. The possible operators are < or lt; <= or le; > or gt; >= or ge; ==, =, or eq; and !=, <>, and ne.
