New Comment:
PS.
If you remove the SET CHARACTER SET UTF-8 stuff, it works. I don't see
why that should screw up pdo sending in lobs though.

Description:
------------
See Ubuntu Bug 137960
I have duplicated this compiling on Mac OS X with the latest CVS
snapshot, so I think its not a Debian/Ubuntu packaging bug.
Reproduce code:
---------------
<?php
$imagesize = getimagesize('dm color logo copy.gif');
$fp = fopen('dm color logo copy.gif', 'rb');
/**
* On Linux/OS X, a 8262 byte image turns into 7966 bytes in the
database
* On Windows, it is stored with the correct size.
*/
$db = new PDO('mysql:host=localhost;dbname=play', 'db_username',
'db_password', array( PDO::MYSQL_ATTR_INIT_COMMAND=>'SET CHARACTER SET
utf8;', PDO::MYSQL_ATTR_MAX_BUFFER_SIZE=>4194304 ) );
$prepared = $db->prepare('INSERT INTO
files
(type,data) VALUES
(:type, :data)');
$prepared->bindParam(':type',$imagesize['mime'], PDO::PARAM_STR, 50);
$prepared->bindParam(':data', $fp, PDO::PARAM_LOB);
$prepared->execute();
$id = $db->lastInsertId();
$prepared = $db->prepare('SELECT type, data FROM
files WHERE
fileid = :fileid');
$prepared->bindParam(':fileid',$id, PDO::PARAM_INT);
$prepared->execute();
$prepared->bindColumn(1, $type, PDO::PARAM_STR, 256);
$prepared->bindColumn(2, $lob, PDO::PARAM_LOB);
$prepared->fetch(PDO::FETCH_BOUND);
header("Content-Type: $type");
echo $lob;
?>
Expected result:
----------------
properly output image as on
http://cowsandmilk.homeip.net/pdolob/pdolobtest.php
Actual result:
--------------
image missing bytes as on http://cowsandmilk.net/pdolob/pdolobtest.php
(goes from 8262 bytes to 7966 bytes)
