Text query to SQL query translator?

Is there a PHP package which is the equivalent of the perl Text-Query-SQL module? <http://www.senga.org/Text-Query-SQL/html/description.html> I am looking for something which takes a query string the average web surfer can understand/produce and turns it into a MySQL query. I am certain something like this has been written, but I cannot seem to find it. From the Text-Query-SQL description: "Text-Query-SQL is derived from the Text-Query module. What is Text-Query then? It is a general purpose query parser and resolver. It is able to parse the AltaVista 'simple query' and 'advanced query' syntax. The resulting syntax tree is then used to build a search query that depends on the database used. Thank you for any pointers! -benjy
