PHP: ibase_blob_get

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.

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