Description

string ibase_blob_get ( resource $blob_handle , int $len )

Note:

Examples

Example #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.
