mysqli - PHP gearman worker with shared DB connection -


i have php worker gearman running command line (through supervisord), acts kind of "api". worker uses mysqli connections retrieve data db , sends connected client.

class my_worker{     private $worker;     static $sql;  public function __construct($sql){      $this->worker = new gearmanworker();     $this->worker->addserver();     self::$sql = $sql;  //register workers     $this->worker->addfunction("testa", array($this, 'testa') );     $this->worker->addfunction("testb", array($this, 'testb') );    }  public function run(){     while ($this->worker->work());  }  static function testa(){ /* select field1 db; fetch row; return serialized; */} static function testb(){ /* select field2 db; fetch row; return serialized; */}  }  //start worker   $sql = new db(sql_host, sql_user, sql_pwd, sql_db); //  extends mysqli class   $worker = new my_worker($sql);   $worker->run(); }

so, have e.g. 2 functions 'testa' , 'testb' selects db. problem share same db connection, if there requests both functions @ same moment, 1 results "wrong" select i.e. testb fetches result select called testa , not testb.

is there way avoid this, except opening separate db connections in each function?

imho, queries handled in parallel , there shouldn't issues current setup. can imagine improved using pdo , transactions

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
