ibase_blob_get — Get len bytes data from open blob
Description

that has been opened for reading by ibase_blob_open().
Note:
It is not possible to read from a BLOB that has been opened for writing
by ibase_blob_create().

len-

Return Values

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.
