Search Query Generator for MySQL Database: Generate an SQL query for searching values

This is a very simple class that can be used to build a SQL WHERE clause for performing a query that search for given field values.

It takes as parameter an associative array with the field names as indexes and the field search parameter values as array entry values.

It generates an SQL SELECT query to retrieve all table fields of the records that match a condition defined by the combination of all fields and values defined by the parameter associative array.
