 *
 * @param string $version1 First version number
 * @param string $version2 Second version number
 * @param string $op If you specify the third optional operator argument,
 *                   you can test for a particular relationship.
 *                   The possible operators are:
 *                   <, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne respectively.
 * @return mixed returns -1 if the first version is lower than the second,
 *               0 if they are equal, and 1 if the second is lower.
 *               When using the optional operator argument, the function will
 *               return TRUE if the relationship is the one specified by the
 *               operator, FALSE otherwise.
