Re: Case insensitivity in column and table names - Mailing list pgsql-php

You could change the key case in the array after having called
pg_fetch_array($resource)
Use the buildin PHP function: array_change_key_case
http://dk.php.net/manual/en/function.array-change-key-case.php

Works for me with Firebird, PostGre and MySQL
