(PHP 4, PHP 5)

ibase_blob_get — Get len bytes data from open blob

### Descripción

string ibase_blob_get ( resource `$blob_handle` , int `$len` )

This function returns at most `len` bytes from a BLOB 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().

### Lista de parámetros

`blob_handle`

  A BLOB handle opened with ibase_blob_open().

`len`

  Size of returned data.

### Valores retornados

Returns at most `len` bytes from the BLOB, or `FALSE` on failure.

### Ejemplos

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.
