Greetings:

Does anyone have any examples of using the pg_loimport routines in PHP?...

I have a requirement to be able to import a binary file (an image) into a table that has three columns.

The first two columns are sequence integers, and the third is an OID column. I would like to be able, via my PHP script, to insert a new image, with the two integers, but I don't see any examples of this for PostGres and PHP... Is this possible to do at all?...

Thanks muchly in advance,
Richard W.

Is it not as straight forward as it looks? I've never used large objects in
PostgreSQL so I really don't know..

From the PHP manual :

>int pg_loimport (int file [, int connection_id])

>The filename argument specifies the pathname of the file to be imported as
a large object. Returns FALSE if an error occurred, object id of the just
created >large object otherwise. Remember that handling large objects in
PostgreSQL must happen inside a transaction.

Looks like file there is a file descriptor returned by fopen() [?] and the
connection ID is that of the PostgreSQL connection.. What happens when you
try it?
