If you are new to PHP or just need to refresh your skills, this is the place to start. This series of tutorials will give you the basic knowledge you will need to create a simple PHP website.

PHP is a reflective programming language originally designed for producing dynamic web pages.[1] PHP is used mainly in server-side scripting, but can be used from a command line interface or in standalone graphical applications. Textual User Interfaces can also be created using ncurses.

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.

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

See also ibase_blob_open(), ibase_blob_close() and ibase_blob_echo().
