New Comment:
Don't use writeTemporary, it's not intended for writing persistent
LOB's.
You should use save() or you can upgrade to PHP5 and use $lob->write()
method.

Description:
------------
first of all I should say that it may be documentation problem, because
didn't find good documentation of the LOB object
i have a oracle procedure, which accepts BLOB
(see the code below)
it inputs the data in the blob but when i extract (with the oracle
tools or with other php script) it is corrupted it is exactly 2 times
larger
when everything is changed to clob (of course the data is text not
jpg), this function work ok
also it is workig for me if I use insert into (the_blob) values
(empty_blob()) returning the_blob into :the_blob
and then bind $lob and use $lob->save
but i don't want to have this
I think $lob->WriteTemporary mangles the data somehow and corrupts it
Reproduce code:
---------------
include_once 'config/environment.inc.php';
$fd = fopen('Sample.jpg', 'r');
$data = fread($fd, filesize('Sample.jpg'));
fclose($fd);
$conn = ocilogon($CFG_DB['username'], $CFG_DB['password'],
$CFG_DB['db']);
$lob = OCINewDescriptor($conn, OCI_D_LOB);
$stmt = OCIParse($conn,"begin TEST_PROC(:the_blob); end;");
OCIBindByName($stmt, ':the_blob', &$lob, -1, OCI_B_BLOB);
$lob->WriteTemporary($data);
OCIExecute($stmt, OCI_DEFAULT);
$lob->close();
$lob->free();
OCICommit($conn);
create procedure TEST_PROC(the_blob blob) is
begin
insert into test_table values (the_blob);
end;
create table test_table (the_blob blob);
