Mientras que mysqli no hace nada con DELIMITER en multi-query sentencias, en realidad no hace nada con ningún delimitador en las consultas normales, así que solo inserte sus disparadores uno por uno:
$ 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 ***************************
