There is an alternative for getting text out of a blob that does not require as much code. Quoted from a handy online resource:

PHP offers natively the possibility of getting the BLOB data as a string.

For example ibase_fetch_assoc ( resource $result [, int $fetch_flag = 0 ] ) provides the $fetch_flag parameter which can be set to IBASE_TEXT, causing the function to return BLOB contents instead of BLOB ids.

here is an example if image.php

<?php
if (isset($_REQUEST['imageid']) AND $_REQUEST['imageid']>0) {
   
$db = 'host:/var/db/mydb.fdb';
   
$dbusername = 'sysdba';
   
$dbpassword = 'masterkey';
   
$query = "SELECT IMAGEDATA, MIME FROM IMAGES WHERE IMAGEID=".$_REQUEST['imageid'];
   
$dbh = ibase_connect($db, $dbusername, $dbpassword, 'UTF8') or die('Couldn't connect DB');
    $result = ibase_query($query);   
    $data = ibase_fetch_object($result);
    if ($data)
    {
        header("Content-type: ".$data->MIME);
        ibase_blob_echo ($data->IMAGEDATA);
    }
    ibase_close($dbh);
}
?>
