Note Submitter: gearond at sbcglobal dot net Reason: bad code ---- This makes a COMB UUID, for the purpose of UUIDs as PRIMARY keys in databases. /* requires installation of ubuntu 'php5_uuid' module * see this URL: http://www.informit.com/articles/printerfriendly.aspx?p=25862 * else, use a search engine and look up "comb uuid", or "sequential uuid" * * returns a guid with the last 12 chars representing the HEX value of time * allow better clustering of database index pages and faster performance * while still using UUIDs * */ function make_comb_uuid(){ uuid_create(&$v4); uuid_make($v4, UUID_MAKE_V4); uuid_export($v4, UUID_FMT_STR, &$v4String); $var=gettimeofday(); return substr($v4String,0,24).substr(dechex($var['sec'].$var['usec']),0,12);
