The cubrid_lob_send function reads BLOB/CLOB data and passes it straight through to the browser. To use this function, you should get BLOB/CLOB information by using the cubrid_lob_get() function.
bool cubrid_lob_send(resource $conn_identifier, resource $lob_identifier )
<?php
$lobs = cubrid_lob_get($con, "SELECT image FROM person WHERE id=1");
Header("Content-type: image/jpeg");
cubrid_lob_send($conn, $lobs[0]);
cubrid_lob_close($lobs);
?>
