ibase_blob_get

(PHP 3>= 3.0.7, PHP 4, PHP 5)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.

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