Question: I want to get the last time my database was updated, so I use this query in my PHP code:

```
$query = mysqli_query($mysqli, "SELECT UPDATE_TIME
                                FROM   information_schema.tables
                                WHERE  TABLE_SCHEMA = 'map_db'
                                AND TABLE_NAME = ".$objects_tab."");
$lastUpdateTime = mysqli_fetch_array($query);
echo "<div id ='lastUpdate'>".$lastUpdateTime."</div>";

```

For some reason the query won't work, does anyone know whats the problem?

It works when I do other queries so its not the `$mysqli` connect variable or the table name variable that's wrong.

Answer: 
I have had the same problem, but I solved it with Notepad++, where I have saved my csv file with encoding to "UTF-8 without BOM" in main menu.
My CSV file looks same, but error message with wrong ID dissappeared.
Extremely late response, but I came to this post after having a similar issue. Deleting the blank, extra sheet in my workbook solved the issue.
