* MySQL storage class for KlarnaPClass
*
* This class is an MySQL implementation of the PCStorage interface.<br>
* Config field pcURI needs to match format:
* user:passwd@addr:port/dbName.dbTable<br>
* Port can be omitted.<br>
*
* <b>Acceptable characters</b>:<br>
* Username: [A-Za-z0-9_]<br>
* Password: [A-Za-z0-9_]<br>
* Address: [A-Za-z0-9_.]<br>
* Port: [0-9]<br>
* DB name: [A-Za-z0-9_]<br>
* DB table: [A-Za-z0-9_]<br>
*
* To allow for more special characters, and to avoid having<br>
* a regular expression that is too hard to understand, you can<br>
* use an associative array:<br>
* <code>
* array(
* "user" => "myuser",
* "passwd" => "mypass",
* "dsn" => "localhost",
* "db" => "mydatabase",
* "table" => "mytable"
* );
