(PHP 5, PHP 7 < 7.4.0)
ibase_blob_get — Get len bytes data from open blob
Description
ibase_blob_get
( resource $blob_handle
, int $len
) : string
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().
Return Values

Examples
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.
