Opret mysql trigger via PHP?

Mens mysqli gør ikke noget med DELIMITER i multi-query udsagn, gør det faktisk ikke noget med nogen afgrænsningstegn overhovedet i normale forespørgsler, så bare skub dine triggere ind én efter én:

$ cat i.php 
<?php
$mysqli = new mysqli('localhost', 'test', '', 'test');
$sql = "
CREATE TRIGGER `_foo_fulltext_update` AFTER UPDATE ON `foo`
  FOR EACH ROW BEGIN
    DELETE FROM `bar` WHERE `bar`=NEW.`bar`;
    INSERT INTO `bar` (bar) SELECT bar FROM `foo` WHERE `bar`=NEW.`bar`;
  END;
";
$mysqli->query($sql);
var_dump($mysqli->error);
$ php i.php 
string(0) ""
$ mysql
mysql> use test;

Database changed
mysql> show triggers\G
*************************** 1. row ***************************
             Trigger: _foo_fulltext_update
               Event: UPDATE
               Table: foo
           Statement: BEGIN
    DELETE FROM `bar` WHERE `bar`=NEW.`bar`;
    INSERT INTO `bar` (bar) SELECT bar FROM `foo` WHERE `bar`=NEW.`bar`;
  END
              Timing: AFTER
             Created: NULL
