it doesn't appear that the php support supports php4.
If one looks at
ezsql_sqlite.php it uses the function
sqlite_fetch_object
from
http://us3.php.net/sqlite_fetch_object
it appears that its only php5.
Another thing to note is that php only supports sqlite2, while for example with debian, MT's perl distribution wont see sqlite2, only sqlite3 (even if both are installed) and hence the php support wont work w/ anything that has to hit the DB.
