API method trends.get automatically filter out non - ITEM_VALUE_TYPE_FLOAT and ITEM_VALUE_TYPE_UINT64 item type, but if one of these types are missed it is possible to catch undefined index:
foreach ([ITEM_VALUE_TYPE_FLOAT, ITEM_VALUE_TYPE_UINT64] as $value_type) {
if ($sql_limit !== null && $sql_limit <= 0) {
break;
}
$sql_from = ($value_type == ITEM_VALUE_TYPE_FLOAT) ? 'trends' : 'trends_uint';
if ($options['itemids'][$value_type]) {
$sql_where['itemid'] = dbConditionInt('t.itemid', array_keys($options['itemids'][$value_type]));
$res = DBselect(
'SELECT '.implode(',', $sql_fields).
' FROM '.$sql_from.' t'.
' WHERE '.implode(' AND ', $sql_where),
$sql_limit
);
while ($row = DBfetch($res)) {
$result[] = $row;
}
if ($sql_limit !== null) {
$sql_limit -= count($result);
}
}
}
when $options['itemids'] does not contain ITEM_VALUE_TYPE_FLOAT or ITEM_VALUE_TYPE_UINT64. So it is possible to cache Undefined index in $options['itemids'][$value_type].
