<para>

|

|
|
that has been opened for reading by <function>ibase_blob_open</function>.
|
|
Returns &false; on failure.

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.

<para>

It is not possible to read from a BLOB that has been opened for writing
