Benim SQL sözdizimi / benim LAMP sunucuda değişkenleri kaçan bazı sorun yaşıyorum.

Ben kullanmak istiyorum komut şöyledir:

$sql=mysql_query("INSERT INTO '$table' (FirstName, LastName, StartDate, TimeStroke, DueDate, Duration, Price, Retailer, Checksum)
VALUES ('$_POST[firstname]','$_POST[lastname]','$_POST[startdate]','$_POST[timestroke]','$duedate','$_POST[duration]','$price','$_SESSION[name]','$random')");

The problem is that sometimes the $table variable contains characters like å, ä and ö. Hence I need to put ' ' around $table to make sure it stays the same. However when doing that recieve the error:

"Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''tablename' (FirstName, LastName, StartDate, TimeStroke, DueDate, Duration, P' at line 1".

Looks like the escaping by ' ' creates a problem. I've tried with replacing the query with a mysql_real_escape_string:

"$sql=sprintf("INSERT INTO '".mysql_real_escape_string($table)."' (FirstName, [...]" 

but that doesnt help me either. Is there a way to keep the data in the variable intact and still be able to run the query? Or do I have to accept that å,ä,ö is banned from php/MySQL?
