database file. (This saves the cost of sqlite reading/parsing the indices).
Persistent db connections have any pending transactions rolled back at request
shutdown time. (non-persistent connections are automatically rolled back when
they are closed).
Enhance sqlite_query() and sqlite_unbuffered_query() to use the C api
sqlite_exec() when the PHP script does not use the return value. This avoids
the extra work and memory allocation for holding result sets when they are not
needed.
function with a similar name.
Change sqlite_query() to use the same mechanism as the unbuffered query; this
moves the bulk of the memory allocations into the ZE memory manager, and will
hopefully be more efficient and less at risk of leaks.
