Примеры

Пример #1 ibase_blob_get() example

<?php
$result    
ibase_query("SELECT blob_value FROM table");
$data      ibase_fetch_object($result);
$blob_data ibase_blob_info($data->BLOB_VALUE);
$blob_hndl ibase_blob_open($data->BLOB_VALUE);
echo         
ibase_blob_get($blob_hndl$blob_data[0]);
?>
Whilst this example doesn't do much more than a 'ibase_blob_echo($data->BLOB_VALUE)' would do, it does show you how to get information into a $variable to manipulate as you please.
