# ibase_blob_get

(PHP 3>= 3.0.7, PHP 4 )

ibase_blob_get -- Get len bytes data from open blob

## Description

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(). Returns `FALSE` on failure.

`<?php $sql = "SELECT blob_value FROM table"; $result = ibase_query($sql); $data = ibase_fetch_object($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.

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