Help in php

I was making a query to change cartoweb's routing module, and I have problems to get the results and put it on the cartoweb enviroment. I want take the results of the route query using direction, with php and postgis/postgresql. I make it, but I have some problems to put the results on a variable and write it down in a result table. I need to put the results of one query on postgresql, using php. I know that the query returns data but I can't get it, from the variables. I need somebody that knows PEAR DB, php and postgresql
