[robertoduran]

if i open a connection at a.php and i do all the queries that I need and i want to do some queries at b.php, Can I do the queries at b.php with the same conection that i opend at a.php OR i have to open and close the connections to the database at each page that use it??

I think connection is close in any case when the code of each page ends...
