If you use this Codesnippet, you can store BLOB to an oracledb!
The next Codesnippet you can view the images!

$dbcon = OCILogon($dbUser,$dbPassword,$dbName);
$query = "select * from IMAGE_DATA where NUM_ID=$id";
$stmt = OCIParse($dbcon, $query);
OCIExecute($stmt, OCI_DEFAULT);
while (OCIFetchInto($stmt, $row, OCI_ASSOC)) {
$data = $row["BLO_IMAGE_DATA"]->load();
}
$type = OCIResult($stmt,"STR_IMAGE_TYPE");
OCIFreeStatement($stmt);

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