php/sqlite3

hi... i've got an issue where i'm trying to incorporate sqlite3 into my php. i'm running fedora 9, php5.2.9. the php app was installed using the tun install process... i know the docs say that php5+ is supposed to have sqlite incorporate natively... however, on this box, it doesn't! when i do a phpinfo(), i get the pdo stuff, but not the sqlite. i went ahead and followed a thread on the php.net that walked through adding sqlite3, using the phpize, and managed to create the sqlite3.so... the phpinfo now has a sqlite section, with a sqlite3.extension_dir that points to the dir that contains the sqlite3.so.. however, when i run a test app using "sqlite_open", i'm getting an error saying that the "sqlite_open" is undefined... so... my question.. how the heck can i resolve this issue! thanks.. -bruce
