 +== Note a few things about this code ==
 +  * The global $config must be set somewhere.
 +  * The $sql_string variable does not have a default value, --it probably should if unsafe users have access(as I rush off to change my own code!)
 +  * mysql has an "improved" extension, but it's not as simple as changing all mysql_ to mysqli_
 +  * this is a generic function, --you might want to use full database.table syntax if using this query out of the box
 +  * There is another way to write queries to take advantage of OOP ([[http://www.php.net/manual/en/ref.mysqli.php|start here]])
