Large Object manipulation

[Anon]

how are large objects opened, closed, and edited in php, hell even in psql's interactive program?

So far I've been able to create a large object but I canot access it through php. any ideas?

mysql_select_db("photo");

$query="SELECT Photo,FileType FROM Photograph WHERE PhotoID=$id";
$result=mysql_query($query);

I use the following code to retrieve a BLOB from mySql and display it on a web page. Is this what you have in mind or maybe you could be more specific:

mysql_select_db("photo");

$query="SELECT Photo,FileType FROM Photograph WHERE PhotoID=$id";
$result=mysql_query($query);

$data=mysql_result($result,0,"Photo");
$type=mysql_result($result,0,"FileType");

Header("Content-type: $type");

print $data;
