/* The testVersion configuration variable may be in any of the following formats:
 * 1) Omitted/empty, in which case no version is specified.  This effectively
 *    disables all the checks provided by this standard.
 * 2) A single PHP version number, e.g. "5.4" in which case the standard checks that
 *    the code will run on that version of PHP (no deprecated features or newer
 *    features being used).
 * 3) A range, e.g. "5.0-5.5", in which case the standard checks the code will run
 *    on all PHP versions in that range, and that it doesn't use any features that
 *    were deprecated by the final version in the list, or which were not available
 *    for the first version in the list.
 * PHP version numbers should always be in Major.Minor format.  Both "5", "5.3.2"
 * would be treated as invalid, and ignored.
 * This standard doesn't support checking against PHP4, so the minimum version that
 * is recognised is "5.0".
