"MySQL is probably the most popular database being used with PHP applications. Sometimes, the databases need to be subject of maintenance tasks like optimizing heavily changed tables or repair tables that may have been affected by some kind of system malfunctioning.
MySQL provides seperate tools to perform these tasks but in the latest versions it was added the possibility request the execution of this kind of operatings via special SQL commands, but on a table by table basis.
This class provides an interface to automate the execution of these maintenance tasks on all tables of a given database.
This is a simple level of automation enables for instance the possibility to schedule the database maintenance operations by executing PHP scripts that use this class to execute the necessary maintenance tasks without human intervention."
