Description:
------------
Can't select blob data from data field (FireBird 2.5.5). 
In PHP 5.6.16 all working perfect !
if use print function result simple is: 0x00000500080

Test script:
---------------
<?
$host = 'localhost:/opt/firebird/examples/test.fdb';
$username = 'sysdba';
$password = 'password';

$dbh = ibase_connect($host, $username, $password);
$query = "SELECT B_DATA FROM TEST2 WHERE ID='9'";
$result = ibase_query($dbh, $query);
$data = ibase_fetch_object($result);
if ($data) {
  header("Content-type: application/pdf");
  header('Content-disposition: attachment; filename="test.pdf"');
  ibase_blob_echo($data->B_DATA);
} else { header('HTTP/1.0 404 Not Found'); }
ibase_close($dbh);
?>
