Semantics
This function opens a blob for reading and sends
its contents directly to standard output (which is the browser, in
most cases). Note that a blob ID is not the same as a blob handle.
If a connection handle is not provided, then the
"default" connection will be used. The default connection
is assigned every time you call fbird_connect or fbird_pconnect, so
if you have multiple connections it will be whichever one was
connected last.
This function returns True on success or False on
failure.
Example
The below example echos a blob to the browser:
$sql = "SELECT blob_value FROM
table ROWS 1 TO 1"; $result = ibase_query($sql); $row
= ibase_fetch_row($result); fbird_blob_echo($row[0]);
